摘要
作为锂离子电池正极材料的锂锰氧化物体系因其价格便宜、安全、无污染,被认为是锂离子电池中最有发展前景的正极材料,但由于其在高温下的循环性能不好,容量衰减较快,大大影响了其商业化的进程。本文对引起LiMn2O4循环稳定性衰减的原因进行了分析,并综述了当前抑制循环容量衰减、提高电性能的方法。
The cathode material of LiMn2O4 is considered as the best material to the lithium-ion secondary battery due to its low price, no pollution and its safety potential.Yet because of the capacity fading at high temperatures,the procedure of its commerical availability is slow. In this paper, several reasons for fading have been analyzed, and its degraded cycling stability and some methods to hinder its capacity fading have also been discussed in order to improve the charge-discharge characteristic.
