【考案の詳細な説明】
この考案は合成樹脂製のケース内に電極群を嵌挿したア
ルカリ電池に係り、ケースのクラックによる電解液の漏
出および水分乾燥による性能劣化を防止することを目的
とする。[Detailed description of the invention] This invention relates to an alkaline battery in which an electrode group is inserted into a synthetic resin case, and its purpose is to prevent leakage of electrolyte due to cracks in the case and performance deterioration due to moisture drying. .
従来、電極群は、電極間の接触を良好に保つために各電
極の積層方向に圧縮された状態で合成樹脂製のケース内
に密に嵌挿されている。Conventionally, an electrode group is tightly fitted into a synthetic resin case in a compressed state in the stacking direction of each electrode in order to maintain good contact between the electrodes.
しかしながら、上記ケースは耐アルカリ性に劣しく、電
極群に保持されている電解液で壁面が濡れると、アルカ
リ性の電解液が壁面を犯し、もろくなって機械的強度が
低下し、電極群の押圧力で、ケース壁面にクラックが生
じて電解液が漏出したり、あるいは高温保存中に、電解
液中の水分がケースの壁面を透過して乾燥し、電池性能
の劣化を来たす。However, the above case has poor alkali resistance, and when the wall surface gets wet with the electrolyte held in the electrode group, the alkaline electrolyte penetrates the wall surface, making it brittle and reducing its mechanical strength. This can cause cracks to form on the case wall and cause the electrolyte to leak out, or during high-temperature storage, moisture in the electrolyte can pass through the case wall and dry up, resulting in deterioration of battery performance.
この考案は上記欠点を解消したもので、以下図面ととも
に説明する。This invention eliminates the above-mentioned drawbacks and will be explained below with reference to the drawings.
１は上面が開口したポリスチロールなどの合成樹脂製の
箱形ケース、２はニッケル陽極３と亜鉛陰極４をセパレ
ータ５を介して交互に積層してなる電極群で、積層方向
に一体に圧縮されてケース１内に直立状態で密に嵌挿さ
れており、ケース１の開口はケース１と同じ材質からな
る蓋体６で密閉されている。1 is a box-shaped case made of synthetic resin such as polystyrene with an open top, and 2 is an electrode group consisting of nickel anodes 3 and zinc cathodes 4 alternately laminated with separators 5 in between, which are compressed together in the lamination direction. The case 1 is tightly fitted in an upright position, and the opening of the case 1 is sealed with a lid 6 made of the same material as the case 1.
ケース１の内壁面７には、基油に増チョウ剤を加えて半
固体状にしたものに、シリコン樹脂あるいはフッ素樹脂
を添加した耐アルカリ性のグリス８が被着されている。The inner wall surface 7 of the case 1 is coated with an alkali-resistant grease 8 made by adding a silicone resin or a fluororesin to a base oil made into a semi-solid by adding a thickening agent.
以上の構成を有するこの考案では、電極群２の押圧力が
作用しても、合成樹脂製のケース１の内壁面７はグリス
８によって電解液が付着せずケース壁面が犯されないか
ら、クラックの発生が抑制され電解液の漏出を防止する
ことができ、また高温保存中でも、ケース１の壁から水
分乾燥がなく電池性能の劣化を防止でき、さらにグリス
８の潤滑作用で電極群２の嵌挿がスムースに行なえる利
点がある。In this invention having the above configuration, even if the pressing force of the electrode group 2 is applied, the electrolyte does not adhere to the inner wall surface 7 of the case 1 made of synthetic resin due to the grease 8, and the case wall surface is not damaged. This prevents leakage of the electrolyte, and even during high-temperature storage, moisture does not dry out from the walls of the case 1, preventing deterioration of battery performance.Furthermore, the lubricating action of the grease 8 prevents the electrode group 2 from being inserted and inserted. It has the advantage that it can be done smoothly.
