尖晶石LiMn₂O₄表面改性的研究与新进展

摘要: LiMn₂O₄作为未来钾离子电池正极材料的基材，一直是人们研究的热点。但高温下与循环中容量衰减的问题, 是制约它商品化的最重要因素。笔者详细阐述了近年来有关尖晶石LiMn₂O₄容量衰减机理和表面改性的研究与最新进展。

Abstract: Lithium manganese oxide is becoming the basic material of Li-ion cells cathode material in the future.As a hot pot, it has been investigated until now. The problem which the capacity is degraded in high temperature and cycling is the most important factor to restrict it commercialize.The researches on the capacity degradation mechanismand and the surface modification of lithium manganese oxide spinel and latest progresses in recent years are related.
