Abstract

　対極にリチウム金属を用いた場合の初期充放電効率が１００％未満の層状酸化物（以下、第１の層状酸化物と呼ぶ）と、上記初期充放電効率が１００％以上の層状酸化物（以下、第２の層状酸化物と呼ぶ）とを混合することにより得られる混合正極活物質を用いる。第１の層状酸化物として、例えばＬｉ1+aＭｎxＣｏyＮｉzＯ2が挙げられる。初期充放電効率が１００％以上の第２の層状酸化物として、酸処理等により予めリチウムが引き抜かれた層状化合物の他に、例えばＬｉAＮａBＭｎXＣｏYＮｉZＯ2等のナトリウム酸化物を用いることができる。上記のＬｉAＮａBＭｎXＣｏYＮｉZＯ2中のナトリウムをリチウムで置換（イオン交換）することにより得られる層状酸化物を第２の層状酸化物として用いることもできる。
