掺杂改性富锂锰基正极材料的研究现状
|
摘要
富锂锰基正极材料因为高的比容量(250-300mAh/g),成为目前研究的热点材料,具有非常高的商业前景,但是其还存在这很多缺点,如循环性能差、不可逆容量高等,基于富锂锰基正极材料的结构特点,综述了通过掺杂来提高富锂锰基正极材料性能的研究现状。
The lithium-rich manganese-based cathode material has great market prospects,due to its high discharge specific capacity(250-300 mAh/g).But it still has many problems,such as poor cycle performance,high irreversible capacity and so on.In this paper,Based on the the structure of the lithium-rich manganese-based cathode material,the research progress in the doped structure was reviewed.
