摘要: 介绍了LiMn2O4材料的各种制备技术,并归之于固相法和液相法两大类,简述了当前LiMn2O4材料研究存在的主要问题及抑制LiMn2O4容量衰减的思路和解决方案.

关键词: LiMn2O4, 制备技术, 控制结晶法, 容量衰减

Abstract: The synthetic methods for the preparation of LiMn2O4 were classified into two methods approximately in this paper, the first called the solid phase method and the other called the liquid phase method. The main obstacles existed in the research of LiMn204 was introduced, and the solutions to restrain the capacity fading were also discussed.

Key words: spinel LiMn2O4, synthetic method, controlled-crystallization, capacity fading
