Description
正極は、正極集電体と、前記正極集電体の表面に形成された正極活物質層とを有するものである。
正極集電体を構成する材料に特に制限はないが、好適には金属が用いられる。具体的には、金属としては、アルミニウム、ニッケル、鉄、ステンレス、チタン、銅、その他合金等などが挙げられる。これらのほか、ニッケルとアルミニウムとのクラッド材、銅とアルミニウムとのクラッド材、またはこれらの金属の組み合わせのめっき材などが好ましく用いられうる。また、金属表面にアルミニウムが被覆されてなる箔であってもよい。なかでも、電子伝導性や電池作動電位の観点からは、アルミニウム、ステンレス、銅が好ましい。
正極活物質層は、正極活物質を含む。本形態において、正極活物質は、リチウムニッケル系複合酸化物およびスピネル系リチウムマンガン複合酸化物を必須に含む。本形態の非水電解質リチウムイオン二次電池は、リチウムニッケル系複合酸化物の含有比率を大きくすることで、リチウムニッケル系複合酸化物に起因するサイクル耐久性および容量がより大きくなる。リチウムニッケル系複合酸化物比率増加による容量増加は、一般にリチウムニッケル系複合酸化物の方がスピネル系リチウムマンガン複合酸化物よりも分子量が小さく、リチウムニッケル系複合酸化物の方が単位質量あたりの反応リチウム数が多いことより得られると考えられる。また、本形態の非水電解質リチウムイオン二次電池は、スピネル系リチウムマンガン複合酸化物を含有することで安全性を向上させることができ、スピネル系リチウムマンガン複合酸化物の含有比率を大きくすることでスピネル系リチウムマンガン複合酸化物に起因する安全性がより高くなる。正極活物質としてリチウムニッケル系複合酸化物およびスピネル系リチウムマンガン複合酸化物を含むことで、リチウムニッケル系複合酸化物およびスピネル系リチウムマンガン複合酸化物の各々の長所を有する優れた正極活物質層が作製できる。
リチウムニッケル系複合酸化物は、リチウムとニッケルとを含有する複合酸化物である限り、その組成は具体的に限定されない。リチウムとニッケルとを含有する複合酸化物の典型的な例としては、リチウムニッケル複合酸化物(LiNiO2)が挙げられる。ただし、リチウムニッケル複合酸化物のニッケル原子の一部が他の金属原子で置換された複合酸化物がより好ましく、好ましい例として、ニッケル、マンガン、コバルトを含有する層状結晶構造のリチウム遷移金属複合酸化物(以下、単に「NMC複合酸化物」とも称する)は、リチウム原子層と遷移金属(Mn、NiおよびCoが秩序正しく配置)原子層とが酸素原子層を介して交互に積み重なった層状結晶構造を持ち、遷移金属Mの1原子あたり1個のLi原子が含まれ、取り出せるLi量が、スピネル系リチウムマンガン酸化物の2倍、つまり供給能力が2倍になり、高い容量を持つことができる。加えて、LiNiO2より高い熱安定性を有しているため、正極活物質として用いられるニッケル系複合酸化物の中でも特に有利である。
スピネル系リチウムマンガン複合酸化物は、典型的にはLiMn2O4の組成を有し、スピネル構造を有する、リチウムおよびマンガンを必須に含有する複合酸化物であり、その具体的な構成や製造方法については、特開2000−77071号公報等の従来公知の知見が適宜参照されうる。
正極活物質層は上述した正極活物質の他、必要に応じて、上述以外の正極活物質、導電助剤、バインダー、電解質(ポリマーマトリックス、イオン伝導性ポリマー、電解液など)、イオン伝導性を高めるためのリチウム塩などのその他の添加剤をさらに含むことができる。
負極活物質層は活物質を含み、必要に応じて、導電助剤、バインダー、電解質(ポリマーマトリックス、イオン伝導性ポリマー、電解液など)、イオン伝導性を高めるためのリチウム塩などのその他の添加剤をさらに含む。
セパレータは、電解質を保持して正極と負極との間のリチウムイオン伝導性を確保する機能、および正極と負極との間の隔壁としての機能を有する。
また、不織布のかさ密度は、含浸させた高分子ゲル電解質により十分な電池特性が得られるものであればよく、特に制限されるべきものではない。さらに、不織布セパレータの厚さは、電解質層と同じであればよく、好ましくは5〜200μmであり、特に好ましくは10〜100μmである。
Oは酸素、およびSは硫黄を表し、
A、BおよびDは、それぞれ独立して、単結合、酸素、硫黄、カルボニル基、チオカルボニル基、スルフィニル基、スルホニル基、およびNR5基からなる群より選ばれる少なくとも1種の基を表し、この際、R5は、水素原子、一価の脂肪族炭化水素基、一価の脂環式炭化水素基および一価の芳香族炭化水素基からなる群より選ばれる少なくとも1種の基を表し、
R1、R2、R3およびR4は、それぞれ独立して、単結合、または二価の脂肪族炭化水素基を表す、で表される化合物であることが好ましい。
Xは炭素数1〜5のアルキレン基、スルホニルアルキレン基、アルケニレン基、スルホニルアルケニレン基である、で表される化合物であることがより好ましい。式(2)における、アルキレン基としては、炭素数1〜3がさらに好ましく、アルケニレン基としては、炭素数2〜3がさらに好ましい。式(2)で表される環式スルホン酸エステルとしては、Xがスルホニルアルキレン基(−SO2−CnH2n−)であるジスルホン酸化合物も含む。ジスルホン酸化合物としては、アルキレン基としては、炭素数1〜3がより好ましい。
Yは炭素数1〜5のアルキレン基、スルホニルアルキレン基、アルケニレン基、スルホニルアルケニレン基である、で表される化合物であることがより好ましい。
集電板(25、27)を構成する材料は、特に制限されず、リチウムイオン二次電池用の集電板として従来用いられている公知の高導電性材料が用いられうる。集電板の構成材料としては、例えば、アルミニウム、銅、チタン、ニッケル、ステンレス鋼(SUS)、これらの合金等の金属材料が好ましい。軽量、耐食性、高導電性の観点から、より好ましくはアルミニウム、銅であり、特に好ましくはアルミニウムである。なお、正極集電板27と負極集電板25とでは、同一の材料が用いられてもよいし、異なる材料が用いられてもよい。
また、図示は省略するが、集電体11と集電板(25、27)との間を正極リードや負極リードを介して電気的に接続してもよい。正極および負極リードの構成材料としては、公知のリチウムイオン二次電池において用いられる材料が同様に採用されうる。なお、外装から取り出された部分は、周辺機器や配線などに接触して漏電したりして製品(例えば、自動車部品、特に電子機器等)に影響を与えないように、耐熱絶縁性の熱収縮チューブなどにより被覆することが好ましい。
電池外装体29としては、公知の金属缶ケースを用いることができるほか、発電要素を覆うことができる、アルミニウムを含むラミネートフィルムを用いた袋状のケースが用いられうる。該ラミネートフィルムには、例えば、PP、アルミニウム、ナイロンをこの順に積層してなる3層構造のラミネートフィルム等を用いることができるが、これらに何ら制限されるものではない。高出力化や冷却性能に優れ、EV、HEV用の大型機器用電池に好適に利用することができるという観点から、ラミネートフィルムが望ましい。また、外部から掛かる発電要素への群圧を容易に調整することができ、所望の電解液層厚みへと調整容易であることから、外装体はアルミニウムを含むラミネートフィルムがより好ましい。ラミネートフィルムの厚さとしては、特に制限はされないが、70〜180μmであることが好ましい。
図2は、二次電池の代表的な実施形態である扁平なリチウムイオン二次電池の外観を表した斜視図である。
一般的な電気自動車では、一回の充電による走行距離(航続距離)は100kmが市場要求である。かような航続距離を考慮すると、電池の体積エネルギー密度は157Wh/L以上であることが好ましく、かつ定格容量は20Wh以上であることが好ましい。
組電池は、電池を複数個接続して構成した物である。詳しくは少なくとも2つ以上用いて、直列化あるいは並列化あるいはその両方で構成されるものである。直列、並列化することで容量および電圧を自由に調節することが可能になる。
本発明の非水電解質リチウムイオン二次電池は、長期使用しても放電容量が維持され、サイクル特性が良好である。さらに、体積エネルギー密度が高い。電気自動車やハイブリッド電気自動車や燃料電池車やハイブリッド燃料電池自動車などの車両用途においては、電気・携帯電子機器用途と比較して、高容量、大型化が求められるとともに、長寿命化が必要となる。したがって、上記非水電解質リチウムイオン二次電池は、車両用の電源として、例えば、車両駆動用電源や補助電源に好適に利用することができる。

リチウムニッケル系複合酸化物として、リチウム以外の遷移金属の組成比(原子比)が、Ni:Mn:Co=50:30:20(原子%)であるNMC複合酸化物(LiNi0.50Mn0.30Co0.20O2)を準備した。ここで、NMC複合酸化物のリチウム以外の遷移金属の組成比(原子比)は、Ni:Mn:Co=50:30:20(原子%)であり、遷移金属原子中に含まれるニッケルの含有比率が、リチウム以外の遷移金属原子の合計量に対して組成比で50原子%である。
負極活物質として人造グラファイト95質量%、ならびに、バインダーとしてポリフッ化ビニリデン(PVDF)(クレハ社製、♯7200)5質量%を用意した。これらをスラリー粘度調整溶媒であるN−メチル−2−ピロリドン(NMP)を適量混合して負極活物質スラリーを調製した。得られた負極活物質スラリーを集電体である銅箔(厚さ:10μm)の表面に塗布し、120℃で3分間乾燥後、ロールプレス機で圧縮成形して平面形状が矩形の負極活物質層を作製した。裏面にも同様にして負極活物質層を形成して、負極集電体(銅箔)の両面に負極活物質層が形成されてなる、塗り終わり部分以外の厚さ140μmの負極を作製した。
エチレンカーボネート(EC)とジエチルカーボネート(DEC)との1:1(EC:DECの体積比)混合溶媒に、リチウム塩としてLiPF6を1.0mol/Lとなるよう溶解させた。この溶液に対して、分子内にS=O結合を有する化合物として1,3−プロパンスルトン(PS)を1.0質量%、ならびに他の添加剤としてビニレンカーボネート(VC)およびフルオロエチレンカーボネート(FEC)をそれぞれ1.0質量%となるよう添加して溶解させ、電解質を作製した。

面内の均一性を維持するため、作製した試験用セルを、試験用セルにかかる圧力が100g/m2となるよう、厚さ5mmのステンレス板で挟んで固定した。この試験用セルを用いて、25℃で0.2C/4.2V_CC/CV充電を7時間行った。次いで、10分間の休止後、0.2C_CC放電で2.5Vまで放電を行った。その後、55℃雰囲気下で1C/4.2V_CC/CV充電(0.0015Cカット)、および1C_CC放電(2.5Vカット)のサイクルを繰り返すことでサイクル試験を行い、1サイクル目の放電容量に対する、300サイクル目における放電容量の値を容量維持率として算出した。得られた試験用セルの容量維持率を下記の表1に示す。なお、容量維持率が高いことは、サイクル耐久性に優れることを表す。
