采用电化学工作站测试了1 mol/L LiODFB (LiPF6) EC+DMC+EMC(1∶1∶1质量比)电解液的热稳定性及其对铝箔集流体的腐蚀性,测试了LTO/Li电池的CV曲线及EIS图谱,并采用电池性能测试系统测试电池的倍率性能和循环性能,探索LiODFB电解液与LiFePO4/LTO电极的相容性.结果表明:在室温和60℃条件下,LiODFB电解液及其对铝箔的稳定性均优于LiPF6电解液,以LiODFB和LiPF6为电解液的LTO/Li电池的CV曲线都具有单一的氧化还原峰,且其首次充放曲线均具有稳定的充放电平台,室温时以LiFePO4/LTO为电极的LiODFB电池和LiPF6电池在0.5C和1C倍率的电池性能相差不大;室温和60℃时LiODFB电池的循环性能均优于LiPF6电池,60℃时尤为显著.
