摘　　要：调研了全球锂离子电池正极材料LiCoO2、LiNiO2、LiMn2O4、LiFePO4 LiNi0.8 Co0.2 O2和Li(CoMnNi)1/3O2的学术研究论文和技术专利申请与授权数按年和语言分布情况。综述了前4种材料作锂离子电池正极材料尚存在的问题和解决对策进展。例如,通过掺杂其他元素、表面包覆、细化材料颗粒及改善正极结构设计来提高正极材料的充放电容量、寿命、功率密度和电池高功率密度使用时的安全性。The annual and linguistic distributions of papers published in academic journals and patents both applied and issued in the world about cathodic materials,such as LiCoO2,LiNiO2,LiMn2O4,LiFePO4,LiNi0.8Co0.2O2 and Li（CoMnNi）1/3O2,for Li-ion battery were investigated.The progresses and challenges in studies on the former four materials for Li-ion battery were reviewed.The improvements of cycling capacities and capacity retentions,and safety of those cathodic materials especially used at high rate charge-discharge,through doping,coating and particle size fining as well as new designing cathodic components were extensively discussed.
