Method for preparing Li1+xMn2-x-yMyO4 for use in lithium batteries |
| 摘要 |
Spinel insertion compounds Li1+xMn2-x-yMyO4 wherein M is a transition metal, 0<x< about 0.33, 0</=y<about 1, can have relatively low surface area at relatively large values of x when prepared with a novel two step heating method. Li1Mn2-yMyO4 is first prepared between a critical temperature, Tc, and about 900 DEG C. Then, a lithium salt is mixed therewith and reacted at a temperature between about 400 DEG C. and Tc. These compounds are suitable for use as a cathode in a lithium battery. The use of LiCl as the lithium salt can provide improved cycle life results in such a battery.
