摘要
富锂锰基正极材料Li2MnO3·LiMO2具有高达300mAh/g的理论容量,并且电压能够达到4.5V,从而具有最高的能量密度,被广泛认为是具有潜力的下一代锂离子正极材料,但是该材料的循环性能以及倍率性能尚不能达到应用要求。本文从机理、合成方法以及材料改性方面综述了富锂锰基正极材料的现状,并且提出了下一步的研究方向。
Lithium-rich layered cathode material Li2MnO3·LiMO2has a high theoretical capacity about 300mAh/g,and the voltage about 4.5V.It is widely considered to be the next-generation lithium ion potential of the positive electrode material with the highest energy density,but the rate performance and cycle performance of this material can't meet the applications demands.The status of the lithium-rich layered cathode material is reviewed from the mechanism of the synthesis methods and material modification terms,and the future research directions are proposed.
