摘要
LiM n2O 4正极材料目前被认为是最具有发展前景的锂离子电池材料,但循环性能差和比容量低是其商业化的最大障碍,对LiM n2O 4正极材料进行其它元素掺杂和表面包覆改性是解决这些问题的最佳方法。综述了近几年来在这方面的研究进展。
LiMn2O4 used as cathode material for Li-ion batteries, had an excellent utilization prospect, but the big obstacle that prevented it from being commercialized was its poor cyclicability and low specific capacity. Doping and surface coating were the best ways to salve these problems. The recent research on modified LiMn2O4 was reviewed in this paper.
