Description
Ca(OH)2+Zn(OH)4 2-+H2O → CaZn(OH)4・H2O+2OH-
などの反応により、CaZn(OH)4などの沈殿物を形成するため、亜鉛のイオンが電解液中を拡散して移動するのを防止することができる。
AgとBiの質量比が100:5となるよう調整されたAgNO3とBi(NO3)3との混合水溶液を作製し、95℃に保たれた50質量%の濃度のKOH水溶液中に徐々に添加して反応させ、精製した沈殿物を水洗乾燥することにより、Ag2OとAg5BiO4とが混在する正極活物質粒子を得た。この正極活物質粒子は、平均粒子径が5μmであり、銀の総量に対するビスマスの総量の割合が質量比で5%であった。
正極活物質とアセチレンブラックと黒鉛粒子との割合を、それぞれ、95.6質量%、0.6質量%および3.8質量%として正極合剤を構成し、この正極合剤80mgを金型に充填し、充填密度5.7g/cm3で、直径5.17mm、高さ0.6mmの円板状に加圧成形することによって、実施例1と同様にして正極合剤成形体(正極合剤層)よりなる正極を作製した。
平均粒子径が5μmのAg2O粒子と、実施例1で作製した正極活物質粒子とを、銀の総量に対するビスマスの総量の割合が質量比で1%となるよう混合し、この混合物を用いて正極を作製した以外は、実施例1と同様にしてアルカリ二次電池を作製した。
AgとBiの質量比が100:10となるよう調整されたAgNO3とBi(NO3)3との混合水溶液を用い、実施例1と同様にして、銀の総量に対するビスマスの総量の割合が質量比で10%の正極活物質粒子を作製した。この正極活物質粒子を用いて正極を作製した以外は、実施例1と同様にしてアルカリ二次電池を作製した。
