摘要

Effect of ionic liquids, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMITFSI) and1-butyl-2,3-dimethylimidazolium bis(trifluoromethanesulfonyl)imide (BDMITFSI), on the Li-O2 cellperformance was investigated by mixing ionic liquids with LiTFSI in TEGDME electrolyte at aspecific volume ratio. Addition of ionic liquids improved the discharge/charge cycleability andoptimum mixing ratio of LiTFSI in TEGDME to ionic liquid was 9 to 1. EMITFSI and BDMITFSIionic liquids reduced the overpotential of oxygen evolution reaction occurred during charging processand BDMITFSI is more effective than EMITFSI. Successive linear sweep voltammetry is inagreement with the observed discharge/charge cycleability.
