電体との密着性が劣るという問題があった。Conventional technology and its problems Thin electrode plates must be used to make thin lead-acid batteries, but the active material tends to fall off the lattice during electrode plate chemical formation and handling of the electrode plates during battery assembly. Further, in the case where the two-split battery case is filled with paste and then joined together, there is a problem in that the adhesiveness between the paste and the current collector is poor.

At the same time, by using a bisected battery case made of two thermoplastic plastics with a structure in which the periphery of the separator is sandwiched between the protrusions and a welded part on the side of the electrode plate surface, problems with conventional thin lead-acid batteries can be solved. This solves the problem.

短絡を防ぐことができる。In manufacturing this battery, unformed or chemically formed electrode plates may be used, but in order to take advantage of the features of the present invention, raw paste with rheological properties is divided into two electrodes with a current collector fixed in advance. It is preferable to apply it into a tank or fill it with a press to form an electrode plate. In any case, the active material is filled into the battery container all at once. After the electrode plates are placed in the battery case, the two halves of the battery case are placed opposite to each other with a separator in between, and the opposing parts of the battery case and the partition wall are heated and welded and joined using a heat mirror or ultrasonic waves. Since pressure is applied from the outside of the battery case during this welding, the electrode plate can be strongly pressed by the separator, that is, with a force of 20 kg/do1 or more. When ultrasonic welding is performed after filling raw paste, the paste moves due to ultrasonic vibration and fills the gaps, so it adheres well to the surface of the current collector. At this time, the raw paste tends to spread along the inner wall of the battery case, but in the battery of the present invention, the separator is sandwiched between the protrusions and the space occupied by the active material is closed, so there is no short circuit between the positive and negative electrode plates. can be prevented.
本発明になる８Ｍ池の極板は電槽内の空問いっばいに配
置されているので、発生ガスによる電解液レベルの上昇
の心配がないもの、即ち酸素サイクルによる密閏形に好
適である。この場合には周知のように排気部には弁機能
を持たせる必要がある。Since the electrode plates of the 8M cell according to the present invention are placed in the open space in the cell, it is suitable for use in a case where there is no need to worry about the electrolyte level rising due to generated gas, that is, a close-contact type using an oxygen cycle. . In this case, as is well known, the exhaust section needs to have a valve function.
酸素サイクルによる密閉電池ではアンチモン・フリー合
金が集電体に用いられる。この合金はアンチモン合金と
比較すると伸びが大きいという傾向があるが、集電体に
よって正極板の周囲を縁どらなければ、集電体の伸びに
よって電槽を破損するおそれが無い。In sealed cells with oxygen cycles, antimony-free alloys are used as current collectors. This alloy tends to elongate more than antimony alloys, but unless the positive electrode plate is surrounded by a current collector, there is no risk of damage to the battery case due to the elongation of the current collector.
発明の効果 本発明の効果を列挙すると次の通りである。Effect of the invention The effects of the present invention are listed below.
活物質が電槽内空間で隙間なく充填しているので、放電
容量が大きい。Since the active material fills the space inside the battery case without any gaps, the discharge capacity is large.
活物質は閉空間内に充填されているので、セパレータ側
部での短絡が無い。Since the active material is filled in the closed space, there is no short circuit on the side of the separator.
極板の側部に電槽の溶着部があり、溶着時に極板はセパ
レータで強く圧迫させることができるので、活物質の脱
落が無い。There is a welded part of the battery case on the side of the electrode plate, and the electrode plate can be strongly pressed by the separator during welding, so the active material does not fall off.
正橋板の集電体が極板の周囲を縁どらないので、伸びに
よる電槽破壊の心配が無い。Since the current collector on the main bridge plate does not border the electrode plate, there is no risk of damage to the battery case due to stretching.
レオロジカルな性質を有する生ペーストを充填したのち
加圧するので、ペーストと集電体との密着が良い。とく
に超音波溶着すれば優れている。Since the raw paste having rheological properties is filled and then pressurized, the paste and the current collector are in close contact with each other. Especially if it is ultrasonic welded, it is excellent.
