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 LiMn 2 O 4 is considered as one of the most promising cathode materials for lithium-ion batteries due to its advantages of environmental friendliness, high safety, abundant manganese resources, low price and non-toxicity. However, LiMn 2 O 4 suffers from charge-discharge cycles To serious capacity loss. Based on this, the influence of nanocrystalline LiMn2O4 on the electrochemical performance was studied, and some other modification methods were briefly introduced.
