Description
反応槽中に、硫酸ニッケルと硫酸コバルトの混合溶液(ニッケル濃度1.45モル/リットル、コバルト濃度0.27モル/リットル)、150g/リットル苛性ソーダ溶液、および25%アンモニア水溶液を、撹拌しつつ同時に滴下し、複合水酸化ニッケルを作成した。この複合水酸化ニッケルを吸引濾過後、水酸化物質量1kgに対して0.5kgの苛性ソーダを加え、5時間、撹拌し、アルカリ洗浄を行い、その後、吸引濾過して、掛水洗浄により、濾過水pHが9.0以下になるまで、洗浄して、サンプルAを得た。また、苛性ソーダを0.2kgにして、サンプルBを得、苛性ソーダを0.1kgにして、サンプルCを得た。
クーロン効率=1回目の放電容量/1回目の充電容量×100 (%)
実施例1の電池特性測定結果を表3に示す。
アルカリ洗浄時の苛性ソーダ添加量を、水酸化物質量1kgに対して2.0kgとした以外は、実施例1と同様の方法で、サンプルDの複合水酸化ニッケルを作製した。
実施例1および比較例1で用いたサンプルA、B、C、D、Eの複合水酸化ニッケルを用いて、水酸化リチウム一水塩の粉末の混合量を75gとした以外は、実施例1と同様の方法で、リチウムニッケル複合酸化物を製造して、サンプルF、G、H、I、Jを得た。
実施例1で得たサンプルA、B、Cの複合水酸化ニッケルを用いて、焼成後のピンミル粉砕を大気中で行い、真空乾燥を行わなかった以外は、実施例1と同様の方法で、サンプルK、L、Mのリチウムニッケル複合酸化物を得た。
