摘要：

The effect of the addition of LiTFSl in both an imidazolium (EMITFSI) and a quaternary ammonium (HTMATFSI) ionic liquid on their conductivities have been estimated. The conductivities of both ionic liquid solutions were markedly decreased when 10 mol% of LiTFSI was dissolved. Ethylene carbonate (EC) and dimethyl carbonate (DMC) were used as additives to improve the conductivity of LiTFSI/ionic liquid solutions. DMC, expected to decrease viscosity, is more effective than EC, expected to dissociate LiTFSI, for HTMA-based system. On the other hand, the contribution of both additives was similar for EMI-based system.
