摘要
研究了尖晶石锰酸锂和钴酸锂混合正极材料在锂离子电池中的应用。在保持锰酸锂与钴酸锂质量比1∶1不变的情况下,对使用该体系的锂离子电池的初始性能、循环性能、过充电性能、60℃荷电保持7d及不同温度放电性能等进行了测试,并与使用纯钴酸锂体系的电池做了比较。结果表明:混合材料满足锂离子电池的要求。
The application of cathode material mixed by spinel LiMn_2O_4 and LiCoO_2 for Li-ion battery was researched. The (performance) of Li-ion battery used the mixed material, such as original character, cycle performance, overcharge performance, full charge storage capability for 7 d at 60 ℃ and discharge capability at different temperatures, were tested when the proportions of LiMn_2O_4 and LiCoO_2 were kept constant(1∶1) and compared with the performance of battery which use pure LiCoO_2.The results showed the mixed material met the demand of Li-ion battery.
