纳米LiMn_2O_4的研究进展

Research progress on LiMn_2O_4 nanostructure

尖晶石型LiMn_2O_4具有环境友好、安全性高、锰资源丰富、价格低廉、无毒等优点,被认为是锂离子电池最有发展前途的正极材料之一,但是在充放电循环过程中LiMn_2O_4遭受到严重的容量损失。基于此,研究了纳米化后的LiMn_2O_4对电化学性能的影响,并简要介绍了一些其他改性方法。

Spinel LiMn2O4 is considered to be one of the most promising anode material for lithium ionic batteries because of its several advantages such as environmental friendly,high safety,abundant manganese resource,low cost and low toxicity.However,during the charge/discharge processes,LiMn2O4 undergoed severe capacity fading.Based on this,the nanostructure effect on electrochemical performance of LiMn2O4 was studied and briefly introduced some other modification methods.
