Abstract

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.

Key words: LiBOB, LiMn₂O₄, electrolyte, cycling performance
