摘要
综述了近年国内外对橄榄石结构的LiCoPO4电极材料的研究现状,包括其晶体结构、制备方法、导电性、磁性能以及电化学脱嵌锂行为。认为该材料的电化学脱嵌锂研究的理论基础意义更高于其实际应用,充电曲线上双电压平台存在的机理仍是公开的待解决难题。
In this paper, the recent situation on the study of the LiCoP（）4 cathode materials has been reviewed, including the crystallographic parameters, preparation technologies, electric con ductivity and electrochemical behavior. It is thought that the study of its electrochemical behavior has more significance in the theoretical investigation than its practical application in commercial lithium battery. The mechanism of the existence of two potential plateaus in the charging profile is still an open question.
