The properties of the binary salt system based on mixtures of methyl ethyl pyrrolidinium bis(trifluoromethane sulfonyl) imide (P12) and lithium bis(trifluoromethane sulfonyl) imide (Li imide) are reported. The lithium containing mixtures were found to be more than two orders of magnitude more conductive than the parent P12 phase and the 33 mol% Li imide systems showed a solid state conductivity around 1×10−4 S/cm at 20°C. This solid state conductivity is believed to take place in plastic crystal phases of the P12 compound.
