Abstract
Description
セイコー電子工業(株)製]を用いて各元素を定量して決定した。
窒素通気のもと、3.5モルの水酸化ナトリウムに0.5モルの硫酸マンガンを加え全量を1Lとし、得られた水酸化マンガンを90℃で1時間熟成させた。熟成後、空気を通気させ90℃で酸化させ、水洗、乾燥後することで酸化マンガン粒子粉末を得た。
炭酸リチウムとZrO2(D50:0.6μm)をLi/Zr=2:1となるように秤量して乳鉢で1時間混合した。この混合物を大気中で1000℃、1200℃、1400℃で5時間焼成した。
参考例1で得られたマンガン酸リチウムに対し、1000℃で焼成したLiとZrの酸化物を該マンガン酸リチウムに対し1wt%秤量添加し、両粉末をボールミルにて1hr乾式混合した。得られたマンガン酸リチウム粒子粉末のMn溶出量は423ppmで、当該粒子粉末からなる正極活物質を用いて作製したコイン型電池は、レート特性は97.7%でサイクル特性は99.0%であった。得られた正極活物質粒子粉末の諸特性を表1に示す。
