LiMn_2O_4 for the Cathode Material of Lithium Ion Secondary Batteries

阐述了近年来LiMn2O4材料在结构、合成和循环性能的研究情况。在结构上,论述了LiMn2O4作为正极材料的理论基础和其在充放电过程中的结构变化。在合成上,论述了合成方法和原材料对性能的影响。在循环性能上,论述了体相掺杂和表面相掺杂两种改善循环性能的方法。

In recent years, LiMn2O4 was one of the highlight of lithium ion secondary batteries. In the paper, the studies on sturcture, synthesis and cycle performance of LiMn2O4 were discussed. In the structure, the theoretical basis of LiMn2O4 for the cathode material and the structural changes during cycling were acounted for. In the synthesis, the effects of synthetical methods and primitive materials on performance were illustrated. And in the cycle performance, the doping and coating, which were two methods improving the cycle performance, were reviewed.
