The numerical values of molar ionic conductivity are summarized in [TFSI] Ils have higher total molar ionic conductivity than 1M LiFSI doped pure EC/DMC carbonate solvents. Furthermore, the relative ionic contribution to the total molar conductivity of each individual cationic and anionic species increase with higher contents of IL in the IL/carbonate mixture, showing that higher carbonate co-solvents have the effects of reducing the molar ionic conductivity. The organic solvents restrict the free motion of the ionic species, resulting in a low conductivity for the organic-based electrolytes, while the IL solvents facilitate the ionic association of the ions, causing a high conductivity for the IL-based electrolytes. Additionally, we realized that the molar ionic conductivity changes in the order ᴧ Li > ᴧ EMI > ᴧ FSI > ᴧ TFSI , indicating that Li + ions have the highest molar ionic conductivity.
