摘要

采用高温固相反应法制备改性的LiMn2O4锂离子电池正极材料.利用SEM、XRD等方法表征产物的结构特性.结果表明:所得产物均具尖晶石型LiMn2O4结构,该样品经Li2CO3改性后用作锂离子电池正极,于常温和高温下的循环性能均得到明显改善.

Abstract

The modified LiMn_2O_4 cathode materials for lithium ion batteries have been synthesized by solid-state reaction. The crystal structure and electrochemical performance of products have been investigated by SEM、XRD and electrochemical measurements. The XRD analysis indicated that all the synthesized products possess Fd3m spinel LiMn_2O_4 structure. Those modified LiMn_2O_4 materials showed improved cycling capacity over pure spinels at high temperature and room temperature.
