Description
〈正極の製法〉
(配合) 導電助剤としてのケッチェンブラックを2重量%、正極活物質としての二酸化マンガン(東ソー社製:HC−9)を94重量%の比率でプラネタリーミキサーを用いて乾式で5分間混合したのち、バインダとしてポリ4フッ化エチレンディスパージョン(PTFE:D−1ダイキン工業社製)4重量%を水に希釈した状態で添加して、湿式で2分間混合した。配合剤中の水分は、固形分100に対し25〜30とした。このケッチェンブラックの比表面積は、1270m2 /gであった。
封口した電池は、1Ωの抵抗で30秒間予備放電し、45℃で24時間保管した後、1Aの低電流で3分間2次予備放電を行った。予備放電後の電池を、室温で7日間エージングし、開路電圧を測定した。
正極合剤を構成する正極活物質、導電助剤およびバインダの配合割合を、以下の表1のごとくとしたこと以外は、実施例1と同様にして実施例2および比較例1ないし4に係る正極シートを得た。
