摘要
采用高温固相合成法制备尖晶石LiMn2O4锂离子电池正极材料,研究合成温度与合成时间对尖晶石LiMn2O4晶体结构和电化学性能的影响。结果表明,尖晶石LiMn2O4晶体结构和电化学性能随合成温度和时间的增加而提高,但合成时间超过24h后对材料结构与性能的影响不大。
The spinal LiMn_2O_4 cathode material for lithium-ion battery is prepared by high temperature solid-state reaction, and the effects of reaction temperature and retention time on the crystalline and electrochemical performance of spinal LiMn_2O_4 are investigated. The results show that crystalline and electrochemical performance are improved with the increase of synthetic temperature and retention time, but the effect is not evident while the retention time is over 24 hours.
