Description

電池用電極の供給装置Battery electrode supply device
　本発明は二次電池等の電極を製造ラインに供給するための供給装置に関する。 The present invention relates to a supply device for supplying an electrode such as a secondary battery to a production line.
　近年、民生用の携帯電話機やポータブル電子機器、携帯情報端末などの急速な小型軽量化及び多機能化に伴い、その電源である電池について、小型軽量、高エネルギー密度、長期間繰り返し充放電可能などの条件を満たす二次電池が要求されている。これらの要求を満たす二次電池として、他の二次電池に比べてエネルギー密度が高いリチウムイオン二次電池が最も有望視されている。そして、より優れたリチウムイオン二次電池を開発すべく、様々な研究開発が行われている。 In recent years, along with the rapid miniaturization and multi-functionalization of consumer mobile phones, portable electronic devices, personal digital assistants, etc., the battery that is the power source is small and light, high energy density, and can be repeatedly charged and discharged for a long time. There is a demand for a secondary battery that satisfies the following conditions. As a secondary battery that satisfies these requirements, a lithium ion secondary battery having a higher energy density than other secondary batteries is considered most promising. Various researches and developments have been conducted to develop better lithium ion secondary batteries.
　また、地球温暖化等の環境問題を踏まえて、太陽光発電システムや風力発電システム等で用いる電力貯蔵システムにリチウムイオン二次電池が利用されるようになってきている。さらに、ＣＯ２削減やエネルギー問題への対策として、低燃費で低排気ガスのハイブリッド自動車（ＨＥＶ：Hybrid　Electric　Vehicle）や電気自動車（ＥＶ：Electric　Vehicle）の普及に期待が高まっており、車載用電池をターゲットにしたリチウムイオン二次電池の開発及び製品化も進んでいる。 In addition, in consideration of environmental problems such as global warming, lithium ion secondary batteries have been used in power storage systems used in solar power generation systems, wind power generation systems, and the like. Furthermore, as a measure against CO 2 reduction and energy problems, there is an increasing expectation for the spread of hybrid vehicles (HEVs) and electric vehicles (EVs) with low fuel consumption and low exhaust gas. Development and commercialization of lithium-ion secondary batteries targeting the above are also in progress.
　このように、リチウムイオン二次電池は、携帯機器のみならず、大型の動力用としての需要も高まっている。リチウムイオン二次電池を動力用や電力貯蔵システムで用いる場合、長時間の放電を可能にするために大容量化する必要があり、サイズも大きくなる。電池のサイズが大きくなるとそれに合わせて電極のサイズも大きくなり、電池の製造ラインにおいて電極を供給する供給装置もそれに対応したものが必要となる。 Thus, the demand for lithium ion secondary batteries not only for portable devices but also for large-scale power is increasing. When a lithium ion secondary battery is used for power or in an electric power storage system, it is necessary to increase the capacity and to increase the size in order to enable long-time discharge. As the size of the battery increases, the size of the electrode increases accordingly, and a supply device for supplying the electrode in the battery production line is also required.
　通常、電極の供給装置はマガジンに積み重ねられている薄板状の電極をバキュームハンドで１枚ずつ取り出し、製造ラインに供給するようになっている。ここで、特に電極のサイズが大きい場合に顕著になる問題として、マガジンから電極が複数枚同時に取り出されるという問題がある。電極が複数枚重なって取り出される原因としては、電極製造時に発生するバリによる密着や、平滑な面どうしが密着することにある。 Usually, the electrode supply device is designed to take out the thin plate electrodes stacked in the magazine one by one with a vacuum hand and supply them to the production line. Here, there is a problem that a plurality of electrodes are taken out from the magazine at the same time, particularly as a problem when the electrode size is large. The reason why a plurality of electrodes are taken out by overlapping each other is due to close contact caused by burrs generated during the manufacture of the electrodes, and smooth surfaces.
　この問題を解決するために、例えば特許文献１には、マガジンの上端開口部に一対の爪を備えた電池用電極の供給装置が開示されている。そして、これら爪がマガジンからバキュームハンドにより電極が取り出される際、電極の外縁に引っ掛かり、その２枚取り出しを阻止すると記されている。 In order to solve this problem, for example, Patent Document 1 discloses a battery electrode supply device having a pair of claws at the upper end opening of a magazine. When the electrodes are taken out from the magazine by a vacuum hand, these claws are caught on the outer edge of the electrodes, and the two pieces are prevented from being taken out.
特開２０００－３４０２９号公報JP 2000-34029 A
　しかしながら、特許文献１の構成では、電極の２枚取り出しを防止するために電極に対する爪の付勢を強くすると電極に傷を付けるおそれがある。一方、電極に傷が付かないように電極に対する爪の付勢を弱くすると、電極が複数枚重なったまま爪を通過するおそれがある。そして、電極が複数枚重なったまま一度爪を通過してしまうと、複数枚の取り出しを阻止することはできない。 However, in the configuration of Patent Document 1, if the urging of the nail against the electrode is increased in order to prevent two electrodes from being taken out, the electrode may be damaged. On the other hand, if the urging of the nail against the electrode is weakened so that the electrode is not damaged, there is a possibility that a plurality of electrodes may pass through the nail while overlapping. Then, once a plurality of electrodes overlap each other and pass through the nail, the removal of the plurality of sheets cannot be prevented.
　また、特許文献１の構成では、電極製造時に発生するバリについては触れられていない。バリが残ったままの電極が使用されると、電池として使用する際にデンドライト析出や短絡といった不具合が生じるおそれがある。 Further, in the configuration of Patent Document 1, no mention is made of burrs that occur during electrode manufacturing. When an electrode with burrs remaining is used, there is a possibility that problems such as dendrite precipitation and short circuit may occur when used as a battery.
　本発明は、電極に傷を付けることなく、電極のバリを取りながらマガジンから電極を１枚ずつ取り出すことができる電池用電極の供給装置を提供することを目的とする。 An object of the present invention is to provide a battery electrode supply device that can take out electrodes one by one from a magazine while removing burrs on the electrodes without damaging the electrodes.
　上記目的を達成するために本発明の電池用電極の供給装置は、上端に開口部を有し、板状の電極を積み重ねて収容するマガジンと、前記開口部から前記電極を吸着して取り出すバキュームハンドと、少なくとも前記電極を取り出す際に電極の外縁に接触する規制部とを備え、前記規制部は、ブラシ又は前記電極の外縁と略平行に並設された複数の突条部であることを特徴とする。 In order to achieve the above object, a battery electrode supply device according to the present invention comprises a magazine having an opening at the upper end, and stacking and storing plate-like electrodes, and a vacuum that adsorbs and takes out the electrode from the opening. A hand and at least a restricting portion that contacts an outer edge of the electrode when the electrode is taken out, and the restricting portion is a brush or a plurality of protrusions arranged substantially parallel to the outer edge of the electrode. Features.
　この構成によると、バキュームハンドで電極を取り出す際に電極が必ず規制部でさばかれる。 に よ る According to this configuration, the electrode is always covered by the restricting part when the electrode is taken out with the vacuum hand.
　上記の電池用電極の供給装置において、前記開口部近傍に設けられた又は前記開口部近傍から前記マガジンの下端まで設けられた枠体を備え、該枠体の内側に前記規制部が設けられることが好ましい。 In the battery electrode supply device described above, a frame body provided near the opening or from the vicinity of the opening to the lower end of the magazine is provided, and the regulation portion is provided inside the frame.

　また上記の電池用電極の供給装置において、前記マガジンは、前記電極を位置決めするガイドシャフトを有することが好ましい。 In the battery electrode supply device, the magazine preferably includes a guide shaft for positioning the electrode.
　また上記の電池用電極の供給装置において、前記マガジンは、前記電極を積載して昇降するステージを有することが好ましい。 In the battery electrode supply apparatus, it is preferable that the magazine has a stage for loading and lowering the electrodes.

　以下では、二次電池の電極を用いて説明するが、本発明の供給装置は他の電池の電極の供給装置にも適用可能である。図１は、本発明の一実施形態の電池用電極の供給装置の斜視図であり、図２は、図１のＡ－Ａ線断面図、図３は電極の断面図である。 Hereinafter, the description will be made using the electrode of the secondary battery, but the supply device of the present invention is also applicable to the supply device of the other battery electrode. FIG. 1 is a perspective view of a battery electrode supply device according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is a cross-sectional view of the electrode.
　電池用電極の供給装置１０は、マガジン１１と、枠体１２と、規制部であるブラシ１３と、台座１４と、バキュームハンド１５とを備えている。 The battery electrode supply device 10 includes a magazine 11, a frame body 12, a brush 13 as a restricting portion, a pedestal 14, and a vacuum hand 15.
　マガジン１１は、板状の電極２０を積み重ねて収容する部材であり、電極２０を位置決めする６本のガイドシャフト１６と、電極２０を積載して昇降するステージ１７とを有する。また、マガジン１１は、その上端にガイドシャフト１６の上端で囲まれて形成された開口部１１ａを有する。 The magazine 11 is a member that stacks and accommodates plate-like electrodes 20, and includes six guide shafts 16 that position the electrodes 20 and a stage 17 that carries the electrodes 20 and moves up and down. The magazine 11 has an opening 11 a formed at the upper end thereof surrounded by the upper end of the guide shaft 16.
　ガイドシャフト１６は、台座１４から上方に延びる円柱状の部材であり、電極２０の端子部を除く電極２０の外縁である３辺にそれぞれ２本ずつ接触するように設けられている。電極２０をそれぞれのガイドシャフト１６に接触するように積み重ねることで、マガジン１１内で電極２０が位置決めされる。 The guide shaft 16 is a columnar member extending upward from the pedestal 14 and is provided so as to come into contact with two sides each of the three sides which are outer edges of the electrode 20 excluding the terminal portion of the electrode 20. By stacking the electrodes 20 so as to be in contact with the respective guide shafts 16, the electrodes 20 are positioned in the magazine 11.
　なお、ガイドシャフト１６は、円柱状に限定されず、角柱状、板状など、積み重ねられた電極２０の側面（外縁）の上下方向に沿って配設される形状であればよい。また、ガイドシャフト１６の数に限定はなく、少なくとも、端子部を除く電極２０の隣り合う何れかの２辺にそれぞれ１つずつ設ければ、位置決めの効果が得られる。なお、ガイドシャフト１６は必須の構成ではなく、枠体１２を支持する他の部材を用いてもよい。 The guide shaft 16 is not limited to a columnar shape, and may be any shape such as a prismatic shape or a plate shape that is disposed along the vertical direction of the side surface (outer edge) of the stacked electrodes 20. Further, the number of guide shafts 16 is not limited, and at least one positioning shaft can be obtained by providing each one on any two adjacent sides of the electrode 20 excluding the terminal portion. The guide shaft 16 is not an essential component, and other members that support the frame body 12 may be used.
　ステージ１７は、エレベーター（不図示）によって支持され、マガジン１１内を昇降することができる。ステージ１７の最上昇位置は枠体１２の下端までである。そして、マガジン１１から電極２０が取り出されることに応じてステージ１７が上昇し、最上段の電極２０が常に同じ高さに保たれる。これにより、バキュームハンド１５は常に一定の動作を行うことでマガジン１１から電極２０を取り出すことができるとともに、製造ラインに電極２０を供給するスピードも一定に保つことができる。なお、ステージ１７は必須の構成ではなく、例えば、台座１４に電極２０を積載するようにしてもよい。 The stage 17 is supported by an elevator (not shown) and can move up and down in the magazine 11. The most elevated position of the stage 17 is up to the lower end of the frame body 12. Then, as the electrode 20 is taken out from the magazine 11, the stage 17 rises, and the uppermost electrode 20 is always kept at the same height. Thus, the vacuum hand 15 can always take out the electrode 20 from the magazine 11 by performing a constant operation, and can also keep the speed at which the electrode 20 is supplied to the production line. Note that the stage 17 is not an essential component, and for example, the electrode 20 may be loaded on the pedestal 14.
　枠体１２は、矩形の額縁状であり、開口部１１ａの近傍、つまりガイドシャフト１６の上端付近を囲むように設けられる。枠体１２の厚みはガイドシャフト１６の長さを超えない範囲で設計することができるが、薄すぎると十分な量のブラシ１３を設けることができないので、数ｃｍ以上の厚みであることが好ましい。なお、枠体１２はコ字型でもよく、その場合、電極２０の端子部側が開口される。なお、枠体１２は必須の構成ではない。 The frame body 12 has a rectangular frame shape, and is provided so as to surround the vicinity of the opening 11a, that is, the vicinity of the upper end of the guide shaft 16. The thickness of the frame body 12 can be designed in a range not exceeding the length of the guide shaft 16, but if it is too thin, a sufficient amount of the brush 13 cannot be provided. . The frame 12 may be U-shaped, and in that case, the terminal portion side of the electrode 20 is opened. The frame 12 is not an essential configuration.
　ブラシ１３は、枠体１２の内側に電極２０の側面へ突出するように設けられ、少なくとも電極２０を取り出す際に電極２０の外縁に接触し、密着している電極２０どうしをさばく役割を有している。図１では、ブラシ１３は電極２０の端子部を除く電極２０の外縁全てに接触するように設けられている。なおブラシ１３は、必ずしも電極２０の端子部を除く電極２０の外縁全てに接触する必要はなく、電極２０の端子部を除く電極２０の外縁の一部に接触する位置に設けた場合でも本発明の効果は得られる。また、ブラシ１３は枠体１３以外の部材に設けるようにしてもよい。 The brush 13 is provided on the inner side of the frame 12 so as to protrude to the side surface of the electrode 20, and at least when the electrode 20 is taken out, it contacts the outer edge of the electrode 20 and has a role of separating the electrodes 20 that are in close contact with each other. ing. In FIG. 1, the brush 13 is provided so as to be in contact with all the outer edges of the electrode 20 except the terminal portion of the electrode 20. Note that the brush 13 does not necessarily need to be in contact with all the outer edges of the electrode 20 except for the terminal portion of the electrode 20, and even in the case where the brush 13 is provided at a position in contact with a part of the outer edge of the electrode 20 except for the terminal portion of the electrode 20 The effect is obtained. Further, the brush 13 may be provided on a member other than the frame body 13.
　電極２０の端子部側にブラシ１３を設けないのは、後述するように、電極２０の端子部は軟らかいので、端子部をブラシ１３でさばいても電極２０どうしの密着を解消することはできないからである。 The reason why the brush 13 is not provided on the terminal portion side of the electrode 20 is that the terminal portion of the electrode 20 is soft, as will be described later, so that even if the terminal portion is covered with the brush 13, the adhesion between the electrodes 20 cannot be eliminated. It is.
　ブラシ１３の材料としては、ポリエステルなどの樹脂を用いることができ、静電気対策の観点からは導電性ポリエステルを用いることが好ましい。導電性の材料を用いた場合はブラシ１３をアース接地する。ブラシ１３の電極２０と重なる部分の長さは、短すぎると付勢が弱く電極の複数枚の取り出しを防止できず、長すぎると付勢が強く１枚も取り出すことができないので、１０～２０ｍｍ程度とすることが望ましい。 As the material of the brush 13, a resin such as polyester can be used, and it is preferable to use conductive polyester from the viewpoint of countermeasures against static electricity. When a conductive material is used, the brush 13 is grounded. If the length of the portion of the brush 13 that overlaps the electrode 20 is too short, the biasing is weak and the removal of a plurality of electrodes cannot be prevented, and if it is too long, the biasing is strong and one cannot be removed. It is desirable to set the degree.
　電極２０はその製法上、ロール状の電極を型で打ち抜いたりスリットしたりして作製するので、その端面にバリが生じやすい。このバリは電極２０表面の活物質であり、電池として使用する際にデンドライト析出や短絡といった不具合を発生する原因となる。上記のブラシ１３によれば、このバリも同時に取り除くことができる。電極２０でバリが生じやすい箇所がわかっていれば、その箇所にブラシ１３を配置することで効果的にバリを除去できる。 Since the electrode 20 is manufactured by punching or slitting a roll electrode with a mold, burrs are likely to occur on the end surface. The burr is an active material on the surface of the electrode 20 and causes problems such as dendrite precipitation and short circuit when used as a battery. According to the brush 13, the burrs can be removed at the same time. If a location where burrs are likely to occur in the electrode 20 is known, the burrs can be effectively removed by arranging the brush 13 at that location.
　台座１４は、供給装置１０の土台であり、マガジン１１を安定して支持できる大きさと重量を有する部材である。 The pedestal 14 is a base of the supply device 10 and is a member having a size and a weight that can stably support the magazine 11.
　バキュームハンド１５は、マガジン１１の上方から下降し、開口部１１ａから最上段の電極２０を吸着して取り出し、製造ラインへ電極２０を供給する装置である。バキュームハンド１５は、図１では１つしか図示していないが、電極２０の大きさに応じて複数用いてもよい。 The vacuum hand 15 is a device that descends from above the magazine 11, sucks and takes out the uppermost electrode 20 from the opening 11a, and supplies the electrode 20 to the production line. Although only one vacuum hand 15 is shown in FIG. 1, a plurality of vacuum hands 15 may be used depending on the size of the electrode 20.
　図３に示すように、電極２０は、端子部２１ａを除いて集電体２１の両面に活物質層２２を有する。例えば、積層型のリチウムイオン二次電池の電極（正極、負極）の一例について説明する。 As shown in FIG. 3, the electrode 20 has an active material layer 22 on both surfaces of the current collector 21 except for the terminal portion 21a. For example, an example of electrodes (positive electrode and negative electrode) of a stacked lithium ion secondary battery will be described.
　正極は、正極集電体の両面に、正極活物質層が坦時された構成を有している。正極集電体は、正極活物質層の集電を行う機能を有している。この正極集電体は、例えば、アルミニウム、チタンなどの金属箔、またはこれらの合金からなる合金箔から構成されており、約１～５００μｍ（例えば約２０μｍ）の厚みを有している。なお、正極集電体としてはアルミニウムが好ましく、その厚みは２０μｍ以下であることが好ましい。また、樹脂の上に金属を被覆した集電体も用いることができる。 The positive electrode has a structure in which a positive electrode active material layer is supported on both sides of a positive electrode current collector. The positive electrode current collector has a function of collecting current from the positive electrode active material layer. The positive electrode current collector is made of, for example, a metal foil such as aluminum or titanium, or an alloy foil made of an alloy of these, and has a thickness of about 1 to 500 μm (for example, about 20 μm). In addition, as a positive electrode electrical power collector, aluminum is preferable and it is preferable that the thickness is 20 micrometers or less. A current collector in which a metal is coated on a resin can also be used.
　また、上記正極集電体は、箔状以外に、フィルム状、シート状、ネット状、パンチ又はエキスパンドされたもの、ラス体、多孔質体、発泡体、繊維群の形成体などの形状であってもよい。 In addition to the foil shape, the positive electrode current collector has a film shape, a sheet shape, a net shape, a punched or expanded shape, a lath body, a porous body, a foamed body, a formed body of fiber groups, and the like. May be.
　正極活物質層は、リチウムイオンを吸蔵・放出し得る正極活物質を含んで構成されている。正極活物質としては、例えば、リチウムを含有した酸化物が挙げられる。具体的には、ＬｉＣｏＯ２、ＬｉＦｅＯ２、ＬｉＭｎＯ２、ＬｉＭｎ２Ｏ４、及び、これら酸化物中の遷移金属を一部他の金属元素で置換した化合物などが挙げられる。中でも、通常の使用において、正極が保有するリチウム量の８０％以上を電池反応に利用し得るものを正極活物質に用いるのが好ましい。 The positive electrode active material layer includes a positive electrode active material capable of inserting and extracting lithium ions. As a positive electrode active material, the oxide containing lithium is mentioned, for example. Specific examples include LiCoO 2 , LiFeO 2 , LiMnO 2 , LiMn 2 O 4 , and compounds in which transition metals in these oxides are partially substituted with other metal elements. Among these, in a normal use, it is preferable to use a material that can utilize 80% or more of the amount of lithium held by the positive electrode for the battery reaction.
　このような正極活物質としては、例えば、ＬｉＭｎ２Ｏ４のようなスピネル構造を有する化合物や、ＬｉＭＰＯ４（Ｍは、Ｃｏ、Ｎｉ、Ｍｎ、Ｆｅから選択される少なくとも１種以上の元素）で表されるオリビン構造を有する化合物などが挙げられる。中でも、Ｍｎ及びＦｅの少なくとも一方を含む正極活物質がコストの観点から好ましい。さらに、安全性及び充電電圧の観点からは、ＬｉＦｅＰＯ４を用いるのが好ましい。ＬｉＦｅＰＯ４は、全ての酸素（Ｏ）が強固な共有結合によって燐（Ｐ）と結合しているため、温度上昇による酸素の放出が起こりにくい。そのため、安全性に優れている。 Examples of such a positive electrode active material include a compound having a spinel structure such as LiMn 2 O 4 and LiMPO 4 (M is at least one element selected from Co, Ni, Mn, and Fe). Examples thereof include compounds having an olivine structure. Among these, a positive electrode active material containing at least one of Mn and Fe is preferable from the viewpoint of cost. Furthermore, it is preferable to use LiFePO 4 from the viewpoint of safety and charging voltage. In LiFePO 4 , since all oxygen (O) is bonded to phosphorus (P) by a strong covalent bond, release of oxygen due to a temperature rise hardly occurs. Therefore, it is excellent in safety.
　なお、上記正極活物質層の厚みは、２０μｍ～２ｍｍ程度が好ましく、５０μｍ～１ｍｍ程度がより好ましい。 In addition, the thickness of the positive electrode active material layer is preferably about 20 μm to 2 mm, and more preferably about 50 μm to 1 mm.
　また、上記正極活物質層は、正極活物質を少なくとも含んでいれば、その構成は特に制限されるものではない。例えば、正極活物質層は、正極活物質以外に、導電材、増粘材、結着材などの他の材料を含んでいてもよい。 The configuration of the positive electrode active material layer is not particularly limited as long as it includes at least the positive electrode active material. For example, the positive electrode active material layer may include other materials such as a conductive material, a thickener, and a binder in addition to the positive electrode active material.
　上記した正極は、例えば、正極活物質、導電材、増粘材及び結着材を混合し、適当な溶剤を加えてペースト状の正極合剤としたものを、正極集電体の表面に塗布乾燥し、必要に応じて電極密度を高めるべく圧縮して形成される。 The positive electrode described above is, for example, a mixture of a positive electrode active material, a conductive material, a thickener and a binder, and an appropriate solvent added to form a paste-like positive electrode mixture on the surface of the positive electrode current collector. Dried and compressed to increase electrode density as needed.
　また上記正極は、平面的に見て矩形形状を有している。短手方向の幅は、例えば、約１５０ｍｍとされており、長手方向の長さは、例えば、約３２０ｍｍとされている。また、正極活物質層の塗布領域（形成領域）は、正極集電体の短手方向の幅と同じ、例えば、約１５０ｍｍとされており、長手方向の長さは、例えば、約３００ｍｍとされている。 Further, the positive electrode has a rectangular shape when seen in a plan view. The width in the short direction is, for example, about 150 mm, and the length in the longitudinal direction is, for example, about 320 mm. The application area (formation area) of the positive electrode active material layer is the same as the width of the positive electrode current collector in the short direction, for example, about 150 mm, and the length in the longitudinal direction is, for example, about 300 mm. ing.
　これにより上記正極は、長手方向の一端に、正極活物質層が形成されずに正極集電体の表面が露出された集電体露出部である端子部を有している。この端子部には、外部に電流を取り出すための、集電リード（不図示）が電気的に接続される。 Thus, the positive electrode has, at one end in the longitudinal direction, a terminal portion that is a current collector exposed portion where the surface of the positive electrode current collector is exposed without forming the positive electrode active material layer. A current collecting lead (not shown) for extracting a current to the outside is electrically connected to the terminal portion.
　一方、負極は、負極集電体の両面に負極活物質層が担持された構成を有している。
負極集電体は、負極活物質層の集電を行う機能を有している。この負極集電体は、例えば、銅、ニッケル、ステンレス鋼、鉄、ニッケルメッキ層などの金属箔、又は、これらの合金からなる合金箔から構成されており、約１μｍ～約１００μｍ（例えば約１６μｍ）の厚みを有している。なお、負極集電体は、銅又はステンレス鋼からなる金属箔が好ましく、その厚みは、４μｍ以上２０μｍ以下であるのが好ましい。また、樹脂の上に金属を被覆した集電体も用いることができる。 On the other hand, the negative electrode has a configuration in which a negative electrode active material layer is supported on both surfaces of a negative electrode current collector.
The negative electrode current collector has a function of collecting current from the negative electrode active material layer. The negative electrode current collector is made of, for example, a metal foil such as copper, nickel, stainless steel, iron, or a nickel plating layer, or an alloy foil made of these alloys, and has a thickness of about 1 μm to about 100 μm (for example, about 16 μm). ). The negative electrode current collector is preferably a metal foil made of copper or stainless steel, and the thickness is preferably 4 μm or more and 20 μm or less. A current collector in which a metal is coated on a resin can also be used.
　また、上記負極集電体は、箔状以外に、フィルム状、シート状、ネット状、パンチ又はエキスパンドされたもの、ラス体、多孔質体、発泡体、繊維群の形成体などの形状であってもよい。 In addition to the foil shape, the negative electrode current collector has a film shape, a sheet shape, a net shape, a punched or expanded shape, a lath body, a porous body, a foamed body, a formed body of fiber groups, and the like. May be.
　負極活物質層は、リチウムイオンを吸蔵・放出し得る負極活物質を含んで構成されている。負極活物質としては、例えば、リチウムを含む物質、あるいは、リチウムの吸蔵・放出が可能な物質からなる。また、高エネルギー密度電池を構成するためには、リチウムの吸蔵／放出する電位が金属リチウムの析出／溶解電位に近いものが好ましい。その典型例としては、粒子状（鱗片状、塊状、繊維状、ウィスカー状、球状、粉砕粒子状など）の天然黒鉛もしくは人造黒鉛が挙げられる。 The negative electrode active material layer includes a negative electrode active material that can occlude and release lithium ions. As the negative electrode active material, for example, a material containing lithium or a material capable of occluding and releasing lithium is used. Further, in order to constitute a high energy density battery, it is preferable that the potential for insertion / extraction of lithium is close to the deposition / dissolution potential of metallic lithium. Typical examples thereof include particulate natural graphite or artificial graphite (scale-like, lump-like, fibrous, whisker-like, spherical, pulverized particle-like, etc.).
　なお、負極活物質として、メソカーボンマイクロビーズ、メソフェーズピッチ粉末、等方性ピッチ粉末などを黒鉛化して得られる人造黒鉛を使用してもよい。また、非晶質炭素を表面付着させた黒鉛粒子を使用することもできる。さらに、リチウム遷移金属酸化物、リチウム遷移金属窒化物、遷移金属酸化物及び酸化シリコンなども使用可能である。リチウム遷移金属酸化物としては、例えば、Ｌｉ４Ｔｉ５Ｏ１２に代表されるチタン酸リチウムを使用すると、負極の劣化が少なくなるため、電池の長寿命化を図ることが可能となる。 As the negative electrode active material, artificial graphite obtained by graphitizing mesocarbon microbeads, mesophase pitch powder, isotropic pitch powder, or the like may be used. Further, graphite particles having amorphous carbon attached to the surface can also be used. Furthermore, lithium transition metal oxides, lithium transition metal nitrides, transition metal oxides, silicon oxides, and the like can also be used. As the lithium transition metal oxide, for example, when lithium titanate typified by Li 4 Ti 5 O 12 is used, the deterioration of the negative electrode is reduced, so that the life of the battery can be extended.
　なお、上記負極活物質層の厚みは、２０μｍ～２ｍｍ程度が好ましく、５０μｍ～１ｍｍ程度がより好ましい。 In addition, the thickness of the negative electrode active material layer is preferably about 20 μm to 2 mm, and more preferably about 50 μm to 1 mm.
　また、上記負極活物質層は、負極活物質を少なくとも含んでいれば、その構成は特に制限されるものではない。例えば、負極活物質層は、負極活物質以外に、導電材、増粘材、結着材などの他の材料を含んでいてもよい。 Further, the structure of the negative electrode active material layer is not particularly limited as long as it includes at least the negative electrode active material. For example, the negative electrode active material layer may include other materials such as a conductive material, a thickener, and a binder in addition to the negative electrode active material.
　上記した負極は、例えば、負極活物質、導電材、増粘材及び結着材を混合し、適当な溶剤を加えてペースト状の負極合剤としたものを、負極集電体の表面に塗布乾燥し、必要に応じて電極密度を高めるべく圧縮して形成される。 The negative electrode described above is, for example, a mixture of a negative electrode active material, a conductive material, a thickener, and a binder, and an appropriate solvent added to form a paste-like negative electrode mixture on the surface of the negative electrode current collector. Dried and compressed to increase electrode density as needed.
　また上記負極は、平面的に見て矩形形状を有している。また、上記負極は、正極よりも大きい平面積に形成されている。上記負極は、短手方向の幅が、正極の幅よりも大きい、例えば、約１５４ｍｍとされており、長手方向の長さが、正極の長さより長い、例えば、約３２４ｍｍとされている。 Further, the negative electrode has a rectangular shape when seen in a plan view. Moreover, the said negative electrode is formed in the plane area larger than a positive electrode. The negative electrode has a width in the short side direction larger than that of the positive electrode, for example, about 154 mm, and a length in the longitudinal direction longer than that of the positive electrode, for example, about 324 mm.
　また、負極活物質層の塗布領域（形成領域）は、短手方向の幅が、負極集電体の幅と同じ、例えば、約１５４ｍｍとされており、長手方向の長さが、例えば、約３０４ｍｍとされている。このため、塗布領域に形成された負極活物質層は、平面的に見て、矩形形状に形成されている。 Further, the negative electrode active material layer application region (formation region) has a width in the short direction equal to the width of the negative electrode current collector, for example, about 154 mm, and a length in the longitudinal direction is, for example, about It is set to 304 mm. For this reason, the negative electrode active material layer formed in the application region is formed in a rectangular shape when seen in a plan view.
　これにより上記負極は、正極と同様、長手方向の一端に、負極活物質層が形成されずに負極集電体の表面が露出された集電体露出部である端子部を有している。この端子部には、外部に電流を取り出すための、集電リード（不図示）が電気的に接続される。 Thus, like the positive electrode, the negative electrode has, at one end in the longitudinal direction, a terminal portion that is a current collector exposed portion where the surface of the negative electrode current collector is exposed without forming the negative electrode active material layer. A current collecting lead (not shown) for extracting a current to the outside is electrically connected to the terminal portion.
　次に、供給装置１０の動作について説明する。ステージ１７の移動により、少なくとも最上段の電極２０がブラシ１３に接触した状態に保たれるか、最上段の電極２０がブラシ１３の下方に位置した状態に保たれる。この状態でバキュームハンド１５が下降して最上段の電極２０の上面に吸着する。この後、バキュームハンド１５が上昇し、吸着した電極２０をマガジン１１の開口部１１ａ、つまり枠体１２から取り出す。このとき、電極２０はその外縁がブラシ１３の付勢力に抗しながらブラシ１３に下側から接触し、ブラシ１３を押しのけながら枠体１２内を通過する。これにより、電極２０が複数枚吸着していた場合、持ち上げられた複数枚の電極２０はブラシ１３の付勢力によって分離され、最上段の電極２０のみが傷が付くことなく取り出される。同時に、ブラシ１３によって電極２０のバリも除去される。 Next, the operation of the supply device 10 will be described. By the movement of the stage 17, at least the uppermost electrode 20 is kept in contact with the brush 13, or the uppermost electrode 20 is kept below the brush 13. In this state, the vacuum hand 15 descends and is attracted to the upper surface of the uppermost electrode 20. Thereafter, the vacuum hand 15 is raised, and the attracted electrode 20 is taken out from the opening 11 a of the magazine 11, that is, the frame body 12. At this time, the outer edge of the electrode 20 comes into contact with the brush 13 from below while resisting the urging force of the brush 13, and passes through the frame 12 while pushing the brush 13 away. Thereby, when a plurality of electrodes 20 are adsorbed, the plurality of lifted electrodes 20 are separated by the urging force of the brush 13, and only the uppermost electrode 20 is taken out without being damaged. At the same time, the burr of the electrode 20 is also removed by the brush 13.
　なお、バキュームハンド１５は電極２０を吸着後に枠体１２内を含む位置で複数回昇降し、該昇降時に電極２０がブラシ１３に接触するようにしてもよい。これにより、電極２０の分離をより確実にし、バリ取りの効果も向上する。 The vacuum hand 15 may be moved up and down a plurality of times at a position including the inside of the frame 12 after attracting the electrode 20, and the electrode 20 may come into contact with the brush 13 during the lifting and lowering. Thereby, the separation of the electrode 20 is further ensured, and the effect of deburring is also improved.
　次に、本発明の電池用電極の供給装置の他の実施形態について説明する。図４は、本発明の一実施形態の電池用電極の供給装置３０の斜視図である。図１と同じ部材には同符号を付し、その詳細な説明を省略する。 Next, another embodiment of the battery electrode supply device of the present invention will be described. FIG. 4 is a perspective view of the battery electrode supply device 30 according to an embodiment of the present invention. The same members as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.
　電池用電極の供給装置３０は、マガジン３１が枠体３２で囲まれて構成されている点で上記の供給装置１０と異なる。図４ではガイドシャフト１６を設けていないが、設けてもよい。枠体３２は、マガジン３１の開口部３１ａからマガジン３１の下端まで設けられた平断面コ字型の部材である。枠体３２の側面の開口面から電極２０をマガジン３１に供給することができる。その際、電極の端子部を開口面側に配置する。なお、その開口面に扉を設け、電極２０をマガジン３１に供給する際に開閉するようにしてもよい。 The battery electrode supply device 30 is different from the above-described supply device 10 in that the magazine 31 is surrounded by a frame 32. Although the guide shaft 16 is not provided in FIG. 4, it may be provided. The frame 32 is a U-shaped member with a flat cross section provided from the opening 31 a of the magazine 31 to the lower end of the magazine 31. The electrode 20 can be supplied to the magazine 31 from the opening on the side surface of the frame 32. In that case, the terminal part of an electrode is arrange | positioned at the opening surface side. A door may be provided on the opening surface, and the door may be opened and closed when the electrode 20 is supplied to the magazine 31.
　ブラシ３３は、枠体３２の内側に電極２０の側面へ突出するように設けられ、少なくとも電極２０を取り出す際に電極２０の外縁に接触し、密着している電極２０どうしをさばく役割を有している。図４では、ブラシ３３は積み上げられた電極２０の端子部を除く電極２０の外縁全てに接触するように設けられている。すなわち、ブラシ３３は枠体３２の上端から下端まで設けられている。なおブラシ３３は、必ずしも電極２０の端子部を除く電極２０の外縁全てに接触する必要はなく、電極２０の端子部を除く電極２０の外縁の一部に接触する位置に設けた場合でも本発明の効果は得られる。ブラシ３３の材料や長さは、上記のブラシ３３と同様とすることができる。 The brush 33 is provided inside the frame body 32 so as to protrude to the side surface of the electrode 20, and has a role of touching the outer edges of the electrode 20 at least when the electrode 20 is taken out and separating the electrodes 20 that are in close contact with each other. ing. In FIG. 4, the brush 33 is provided in contact with all the outer edges of the electrode 20 except for the terminal portions of the stacked electrodes 20. That is, the brush 33 is provided from the upper end to the lower end of the frame body 32. Note that the brush 33 is not necessarily in contact with the entire outer edge of the electrode 20 except for the terminal portion of the electrode 20, and the present invention is provided even when the brush 33 is provided at a position in contact with a part of the outer edge of the electrode 20 except for the terminal portion of the electrode 20. The effect is obtained. The material and length of the brush 33 can be the same as those of the brush 33 described above.
　供給装置３０の動作としては、ステージ１７の移動により、最上段の電極２０が定位置に保たれる。この状態でバキュームハンド１５が下降して最上段の電極２０の上面に吸着する。この後、バキュームハンド１５が上昇し、吸着した電極２０をマガジン３１の開口部３１ａ、つまり枠体３２から取り出す。このとき、電極２０はその外縁がブラシ３３の付勢力に抗しながらブラシ３３に接触し、ブラシ３３を押しのけながら枠体１２内を通過する。これにより、電極２０が複数枚吸着していた場合、持ち上げられた複数枚の電極２０はブラシ３３の付勢力によって分離され、最上段の電極２０のみが傷が付くことなく取り出される。同時に、ブラシ３３によって電極２０のバリも除去される。また、電極２０のバリはステージ１７の移動時にも除去される。 As the operation of the supply device 30, the uppermost electrode 20 is maintained at a fixed position by the movement of the stage 17. In this state, the vacuum hand 15 descends and is attracted to the upper surface of the uppermost electrode 20. Thereafter, the vacuum hand 15 is raised, and the attracted electrode 20 is taken out from the opening 31 a of the magazine 31, that is, the frame body 32. At this time, the outer edge of the electrode 20 contacts the brush 33 while resisting the urging force of the brush 33, and passes through the frame 12 while pushing the brush 33 away. Thus, when a plurality of electrodes 20 are adsorbed, the plurality of lifted electrodes 20 are separated by the urging force of the brush 33, and only the uppermost electrode 20 is taken out without being damaged. At the same time, the burr of the electrode 20 is also removed by the brush 33. Further, the burr of the electrode 20 is removed when the stage 17 is moved.
　なお、供給装置１０と同様に、バキュームハンド１５は電極２０を吸着後に枠体３２内で複数回昇降し、該昇降時に電極２０がブラシ１３に接触するようにしてもよい。これにより、電極２０の分離をより確実にし、バリ取りの効果も向上する。 Note that, similarly to the supply device 10, the vacuum hand 15 may move up and down a plurality of times within the frame 32 after attracting the electrode 20, and the electrode 20 may come into contact with the brush 13 during the lifting and lowering. Thereby, the separation of the electrode 20 is further ensured, and the effect of deburring is also improved.
　次に、本発明の電池用電極の供給装置のさらに他の実施形態について説明する。図５は、本発明の一実施形態の電池用電極の供給装置４０の断面図である。図２と同じ部材には同符号を付し、その詳細な説明を省略する。 Next, still another embodiment of the battery electrode supply device of the present invention will be described. FIG. 5 is a cross-sectional view of the battery electrode supply device 40 according to an embodiment of the present invention. The same members as those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted.
　電池用電極の供給装置４０は、規制部としてブラシ１３の代わりに突条部４３を用いている点で上記の供給装置１０と異なる。突条部４３は、電極２０の外縁と略平行に複数並設されている。突条部４３は、三角柱の部材であり、１つの頂辺が電極２０の側面へ突出するように、枠体１２の内側に水平に複数段設けられている。換言すれば、複数の突条部４３が並設されていることにより、凹凸による溝が形成されているとも言える。そして、突条部４３は少なくとも電極２０を取り出す際に電極２０の外縁に接触し、密着している電極２０どうしをさばく役割を有している。 The battery electrode supply device 40 is different from the above-described supply device 10 in that a protruding portion 43 is used instead of the brush 13 as a regulating portion. A plurality of protrusions 43 are arranged in parallel with the outer edge of the electrode 20. The protrusion 43 is a triangular prism member, and is provided in a plurality of stages horizontally on the inner side of the frame body 12 so that one top side protrudes to the side surface of the electrode 20. In other words, it can be said that a plurality of protrusions 43 are arranged side by side, so that grooves due to irregularities are formed. And the protrusion 43 has a role which contacts the outer edge of the electrode 20 at the time of taking out the electrode 20 at least, and discriminates the electrodes 20 which are closely_contact | adhered.
　なお、突条部４３の断面形状は三角形に限らず、四角形等の多角形や先端が円弧状となった形状などでもよい。また突条部４３は少なくとも２以上並設されていればよいが、その数が多いほど効果が大きい。 The cross-sectional shape of the protrusion 43 is not limited to a triangle, but may be a polygon such as a quadrangle or a shape whose tip is an arc. Moreover, although the protrusion part 43 should just be arranged at least 2 or more in parallel, an effect is so large that the number is large.
　図５では、突条部４３は電極２０の端子部を除く電極２０の外縁全てに接触するように設けられている。なお突条部４３は、必ずしも電極２０の端子部を除く電極２０の外縁全てに接触する必要はなく、電極２０の端子部を除く電極２０の外縁の一部に接触する位置に設けた場合でも本発明の効果は得られる。突条部４３の材料や突出の長さは、上記のブラシ１３と同様とすることができる。 In FIG. 5, the protrusion 43 is provided so as to be in contact with all the outer edges of the electrode 20 except for the terminal portion of the electrode 20. The protrusion 43 does not necessarily need to be in contact with the entire outer edge of the electrode 20 except for the terminal portion of the electrode 20, and even when provided at a position in contact with a part of the outer edge of the electrode 20 except for the terminal portion of the electrode 20. The effect of the present invention can be obtained. The material of the protrusion 43 and the length of the protrusion can be the same as those of the brush 13 described above.
　供給装置４０の動作としては、ステージ１７の移動により、少なくとも最上段の電極２０が突条部４３に接触した状態に保たれるか、最上段の電極２０が突条部４３の下方に位置した状態に保たれる。この状態でバキュームハンド１５が下降して最上段の電極２０の上面に吸着する。この後、バキュームハンド１５が上昇し、吸着した電極２０をマガジン４１の開口部４１ａ、つまり枠体１２から取り出す。このとき、電極２０はその外縁が突条部４３の付勢力に抗しながら突条部４３に下側から接触し、突条部４３を押しのけながら枠体１２内を通過する。これにより、電極２０が複数枚吸着していた場合、持ち上げられた複数枚の電極２０は突条部４３の付勢力によって分離され、最上段の電極２０のみが傷が付くことなく取り出される。同時に、突条部４３によって電極２０のバリも除去される。 As the operation of the supply device 40, at least the uppermost electrode 20 is kept in contact with the ridge 43 by the movement of the stage 17, or the uppermost electrode 20 is positioned below the ridge 43. Kept in a state. In this state, the vacuum hand 15 descends and is attracted to the upper surface of the uppermost electrode 20. Thereafter, the vacuum hand 15 is raised, and the attracted electrode 20 is taken out from the opening 41 a of the magazine 41, that is, the frame body 12. At this time, the outer edge of the electrode 20 comes into contact with the protrusion 43 from below while resisting the urging force of the protrusion 43, and passes through the frame 12 while pushing the protrusion 43 away. Thereby, when a plurality of electrodes 20 are adsorbed, the plurality of lifted electrodes 20 are separated by the urging force of the protrusion 43, and only the uppermost electrode 20 is taken out without being damaged. At the same time, the burrs of the electrode 20 are also removed by the protrusions 43.
　なお、バキュームハンド１５は電極２０を吸着後に枠体１２内を含む位置で複数回昇降し、該昇降時に電極２０が突条部４３に接触するようにしてもよい。これにより、電極２０の分離をより確実にし、バリ取りの効果も向上する。 The vacuum hand 15 may be moved up and down a plurality of times at a position including the inside of the frame 12 after the electrode 20 is sucked, and the electrode 20 may contact the protrusion 43 during the lifting and lowering. Thereby, the separation of the electrode 20 is further ensured, and the effect of deburring is also improved.
