Abstract

層状構造を有し、少なくともＬｉとＮｉと元素Ｘを含むリチウム金属複合酸化物粉末であって、下記に定義するＲの累積頻度分布曲線において、全体を１００％としたときに、前記Ｒの小さい側からの累積頻度が９０％となる点のＲの値であるＲ（９０）が１．７以上３．７以下であるリチウム金属複合酸化物粉末。Ｒとは、リチウム金属複合酸化物粉末に含まれるリチウム金属複合酸化物一粒子における、ニッケルと元素Ｘとの物質量の総和であるＮｉ＋Ｘに対する、酸素の物質量をＯとしたときの比であるＯ／（Ｎｉ＋Ｘ）の値である。ニッケル、元素Ｘ及び酸素の物質量は、リチウム金属複合酸化物一粒子について、加速電圧を１１００Ｖとしたエネルギー分散型Ｘ線（ＥＤＸ）分光法により求める。
