摘　　要：LiNi_(0.5)Mn_(1.5)O_4具有三维锂离子传输通道、4.7V的高平台电压,成为最有潜力的锂离子动力电池正极材料之一。但是,过渡金属Mn易溶于电解液,使电池循环性能和倍率性能变差。总结了Li_(0.5)Mn_(1.5)O_4正极材料的改性进展,在此基础上,提出了材料改性的研究方向。LiNi0.5Mn1.5O4 has been one of the most promising cathode materials for LIBs owe to its high operating voltage（ 4. 7 V）,three dimensional channels for Li＋-ion diffusion. However,the poor rate capability and cycle performance of LiNi0.5Mn1.5O4 due to the dissolution of Mn ions. In order to overcome the drawback,material modification has been done. In this paper,the progress on modification of LiNi0.5Mn1.5O4 has been reviewed,and research directions of material modification have been proposed.
