To investigate physicochemical relationships between ionic radii, valence number and cationic metal species in electrolyte solutions, propylene carbonate with Li[N(SO2CF3)(2)], Na[N(SO2CF3)(2)], Mg[N(SO2CF3)(2)](2) and Ca[N(SO2CF3)(2)](2) were prepared. The temperature dependence of density, viscosity, ionic conductivity (AC impedance method) and self-diffusion coefficient (pulsed-gradient spin-echo nuclear magnetic resonance) was measured. The effects of cationic radii and cation valence number on the fluidity and transport properites (conductivity and self-diffusion coefficient) were analyzed. (C) The Author(s) 2018. Published by ECS.
