【考案の詳細な説明】
本考案は積層形有機電解質電池の改良に関する
ものである。[Detailed Description of the Invention] The present invention relates to improvement of a stacked organic electrolyte battery.
従来より、陰極活物質としてリチウム、ナトリ
ウム等の軽金属を用い、また陽極活物質として金
属酸化物、硫化物、塩化物等を用い、更に、電解
液としてプロピレンカーボネート、γ−ブチロラ
クトン等の有機溶媒に過塩素酸リチウム、四塩化
アルミニウム等の無機塩を溶解させた有機電解質
電池は種々提案されている。また、大きな放電容
量を得るため、複数の電池を直列につないだ積層
有機電解電池も提案されている。 Conventionally, light metals such as lithium and sodium have been used as cathode active materials, metal oxides, sulfides, chlorides, etc. have been used as anode active materials, and organic solvents such as propylene carbonate and γ-butyrolactone have been used as electrolytes. Various organic electrolyte batteries have been proposed in which inorganic salts such as lithium perchlorate and aluminum tetrachloride are dissolved. Furthermore, in order to obtain a large discharge capacity, a stacked organic electrolytic battery in which a plurality of batteries are connected in series has also been proposed.
しかしながら有機電解質電池は陽極端子と陰極
端子を短絡させた場合、高熱を発生し、有機電解
液の蒸気圧が高くなつて、電池を破損させる虞れ
があつた。また、この問題を解決するため電槽蓋
の一部を薄肉にし、急激に蒸気圧が高くなつた場
合は、この薄肉部を破損せしめ、電池全体が損傷
しないようにしたものは提案されている（例えば
特公昭39−3169）。しかし、この薄肉部を破損さ
せると、その部分から電解液が漏洩する虞れがあ
るので、一度短絡させた電池は、仮にエネルギー
が残つていても、時後使用できないことになる。 However, when an anode terminal and a cathode terminal of an organic electrolyte battery are short-circuited, high heat is generated and the vapor pressure of the organic electrolyte increases, which may damage the battery. In addition, in order to solve this problem, it has been proposed to make a part of the battery case lid thin so that if the vapor pressure suddenly increases, this thin part will be damaged and the entire battery will not be damaged. (For example, Tokuko Sho 39-3169). However, if this thin part is damaged, there is a risk that the electrolyte will leak from that part, so a short-circuited battery will no longer be usable even if it has some energy left.
本考案はかかる従来例の難点に鑑みてなされた
もので、水密性および通気性を有する厚肉部材に
て形成された電槽若しくは電槽蓋に、薄肉部が形
成され、電解液の蒸気がこの薄肉部を通つて外部
に逃げ、薄肉部も破損しないようにしたものであ
る。 The present invention has been developed in view of the drawbacks of the conventional examples, and a thin wall portion is formed on the battery case or the battery case lid, which is made of a thick walled material having watertightness and air permeability. It escapes to the outside through this thin wall part, so that the thin wall part is not damaged.

In the figure, 1 is a battery case, and a battery case 2 made of thick polypropylene resin is installed inside the battery case. This battery case 2 is divided into three rooms, and each room is equipped with electrode bodies 7, 7', 7'' formed by laminating an anode plate 4 and a cathode plate 5 with a separator 6 in between. The anode plate 4 of the battery used in the above is made of a mixture of 88% by weight of heat-treated manganese dioxide as an anode active material, 10% by weight of acetylene black as a conductive agent, and 2% by weight of an aqueous polyvinyl alcohol solution as a viscous agent. % and knead to form a paste, fill this with a stainless wire mesh, dry it and then roll it.Also, the cathode plate 5
is made of a lithium thin plate, and the separator 6 is made of a polypropylene nonwoven fabric, which is impregnated with an organic electrolyte. 8 and 8' are the electrode bodies 7 and 8 in each room.
