富锂固溶体正极材料xLi2 MnO3·(1-x)LiMO2 (M=Co,Ni,Mn…),首次不可逆容量很大程度上与组分中的Li2MnO3电化学过程有关.富锂固溶体正极材料4.5V区域充电平台是组分中Li2MnO3电化学活化过程；Li2MnO3首次循环不可逆容量较大,约在50～100 mAhg-1,4.5V电位脱出Li+同时脱出O2-,等效脱出不可嵌入的Li2O;Li:MnO3与分解的电解液发生离子交互反应后,H+占据不可逆位置,阻碍了Li+的嵌入；多周循环晶体结构改变,形成不可逆结构并有新相生成.本文综合介绍近几年关于Li2 MnO3结构、常温脱嵌锂机理、高温下电解液分解及循环后结构变化等方面的研究现状.
