Description
「電池便覧」、丸善株式会社、第74〜77頁
酸化亜鉛粉末99質量部と酸化アルミニウム粉末1質量部とを混合し、得られた混合物を成形した後、1300℃で3時間焼成し、炉冷後、成形物を乳鉢ですりつぶして、アルミニウムをドープさせた酸化亜鉛の粉末を得た。この酸化亜鉛におけるアルミニウムのドープ量は1質量%であった。
実施例1と同様の正極を用い、ゲル状電解液には水酸化カリウムを35質量%含有し、かつ通常の酸化亜鉛を2.4質量%含有するアルカリ電解液を用い、組立電解液に水酸化カリウムを35質量%含有し、かつ実施例1と同様のアルミニウムをドープさせた酸化亜鉛を2.4質量%含有するアルカリ電解液を用い、それ以外は実施例1と同様にアルカリ一次電池を作製した。
実施例1と同様の正極を用い、組立電解液、ゲル電解液ともに水酸化カリウムを35質量%含有し、かつ通常の酸化亜鉛を2.4質量%含有するアルカリ電解液を用い、それ以外は実施例1と同様にアルカリ一次電池を作製した。
