Abstract

The rate property of Li/LiCoO2 cell using ionic liquids (ILs) containing fluorosulfonyl(trifluoromethylsulfonyl) amide (FTA-) anion and N,N-diethyl-N-methyl-N-(2-methoxyethyl)ammonium (DEME+) was investigated, comparing with corresponding amide ionic liquids composed of such bis(trifluoromethyl)sulfonylamide (TFSA-) and bis(fluoromethylsulfonyl)amide (FSA-). As a result, the cell using DEME[FTA] was also exhibit good rate performance as in the case of DEME[FSA]. This result suggests that an existence of FSO2 group in anionic species might be a key factor to improve the battery performance containing neat ILs.
