| 摘 要： | 为提高锰酸锂的高温循环性能，以草酸、硼酸、氢氧化锂为原料，用固相法合成锂盐LiBOB；并利用X射线衍射（XRD）、扫描电子显微镜（SEM）、傅立叶变换红外光谱仪（FTIR）、热重-差热分析（TG-DTA）对锂盐结构、形貌及热稳定性进行表征和测试；研究了LiBOB/EC+PC+EMC体系对锰酸锂高温循环性能的影响.实验结果表明，LiBOB具有良好的结晶性和热稳定性，1 C倍率下锰酸锂电池高温循环200次后，容量保持率为97.15%.

| Abstract: | In order to improve the cycling performance of LiMn2O4 at elevated temperature,LiBOB was synthesized with solid state method using oxalic acid,boric acid and lithium hydroxide as raw materials,and the structure,morphology and thermal stability of lithium salt were characterized and measured by XRD,SEM,FTIR and TG-DTA,respectively.Meanwhile,effect of LiBOB/EC+PC+EMC on the cycling performance of LiMn2O4 at elevated temperature was studied,and the results show that LiBOB has good crystallinity and thermostability,after 200 cycles,the LiMn2O4/Li cell retained 97.15% of its initial discharge capacity at 1 C-rate after cycled at elevated temperature. |
