“…The demand for these energy storage devices results from the increased use of renewable energy-a characteristic of which is the discontinuous generation of energy. Molecular solvents can be used as additives in ionic liquid electrolytes to increase conductivity, thus providing electrolytes with well-balanced liquid range, safety and performance [8]. Nevertheless, one of the main advantages resulting from the use of undiluted ionic liquids-the significantly increased thermal stability-is thereby partially reduced [9].…”

“…Thermal transitions of the pristine membrane, related to the crystallization of carbonates, are almost suppressed upon the activation in 0.7 M LiBOB EC : PC : DMC. The activated sample does not show any crystallization/melting transition; in particular, the endo‐thermic melting process around 0 °C disappears upon activation, which is favorable for low temperature applications since the crystallization causes conductivity to plummet . Only a glass transition is observed around −85 °C in the activated sample.…”

“…The model predictions accurately capture this trend. The current conventional electrolyte LP30 found in Li-ion batteries consists of 1 M LiPF 6 in 1:1 ethyl carbonate (EC) and dimethylcarbonate (DMC) mixture that is known to have an ionic conductivity of 1.26 at 298.15 K 93,94 . Thus for ionic liquids to be considered as a potential electrolyte additive to replace LP30, the ionic conductivity target should at least be close to 2.0 S/m as the addition of Li salts dramatically reduces the ionic conductivity and increases viscosity by 30-50% 80,95,96 .…”
