摘　　要：尖晶石型LiMn2O4以其高能量密度、价格低廉、无环境污染等特点而被视为最具发展潜力的锂离子电池的正极材料之一,但循环过程容量的衰减制约了它商品化。体相掺杂和表面修饰是抑制尖晶石型LiMn2O4容量衰减的有效方法。详细阐述了近年来关于LiMn2O4在掺杂和表面修饰方面的最新研究进展。Spinel LiMn2O4 is a potential cathode material of Li-ion batteries because of its high energy density, low cost and no pollution to environment, etc. The capacity degrades in cycling which restricts it to be commercialized. Doping and surface modification are the effectively ways to restrain the capacity loss in cycling. The research progress on doping and surface modification of LiMn2O4 was introduced in detail in this paper.
