尖晶石LiMn2O4的制备与改性

尖晶石LiMn2O4是很有发展前途的锂二次电池正极材料,但它在循环过程中存在容量衰减,如何解决这-问题是实现该材料工业化的前提.众多的研究都集中在稳定尖晶石的结构上,概述了在采用的原料,合成温度,掺杂及包覆改性方.面的研究进展.

The preparation and modification of spinel LiMn2O4

The spinel LiMn2O4 was the most promising cathode material for secondary lithium battery. There was still some questions prevented its use in industry such as the fade of the capacity in recycles. So most of the research was concerned in how to enhance its structure. A review of the progress made these years, including the chose of material, the preparation temperature, the doping ions and coating the cathode was given.
