摘要
5V高电压正极材料因其较高的能量密度被人们广泛关注及研究。综述了多种锂离子电池高电压正极材料,重点分析了橄榄石结构的LiCoPO4和LiNiPO4、尖晶石型的LiNi0.5Mn1.5O4以及反尖晶石结构的LiNiVO4正极材料的研究状况,并评价了高电压正极材料的未来发展趋势。
5 V cathode materials have attracted by many researchers due to their relatively higher energy density. The experimental and theoretical research work of the 5 V cathode materials are intensively summerized, including olivined LiCoPO4 and LiNiPO4, spinel LiNi0. 5Mn1. 5 04, and inverse spinel LiNiVO4, etc. In addition, the research prospects of these 5 V cathodes are evaluated.
