Description
【０００５】
【課題を解決するための手段】本発明は、水酸化ニッケルを活物質の主体とする正極と、負極と、セパレータおよび水酸化カリウムと水酸化ナトリウムと水酸化リチウムとを含有するアルカリ電解液を備えたアルカリ蓄電池であって、正極にはコバルト化合物と亜鉛化合物が含有され、かつ電解液に亜鉛が含有されていること、また、電解液に含有されている亜鉛が、０．１〜１Ｍであること、さらに、正極に含有されている亜鉛化合物の量が、水酸化ニッケルに対する亜鉛の量に換算して１〜１０ｗｔ％であることを特徴とする
なお、活物質の水酸化ニッケルには、コバルトおよび亜鉛が共沈されている場合に、その効果が大きい。
[0005]
[0005] The present invention provides an alkaline storage battery comprising a positive electrode whose active material is mainly nickel hydroxide, a negative electrode, a separator, and an alkaline electrolyte containing potassium hydroxide, sodium hydroxide, and lithium hydroxide , wherein the positive electrode contains a cobalt compound and a zinc compound, and the electrolyte contains zinc, the zinc content of the electrolyte is 0.1 to 1 M, and the amount of zinc compound contained in the positive electrode is 1 to 10 wt % calculated as the amount of zinc relative to the nickel hydroxide. Note that the effect is greatest when cobalt and zinc are coprecipitated in the nickel hydroxide active material.
