conductivity of σ = 8.9 × 10−3 S·cm−1. The temperature dependence of the prepared polymergelelectrolytes follows the thermally activated behavior of the Vogel–Tammann–Fulcher equation. The total ionic transference number was ≈0.91 with a wider electrochemical potential window of 4.0 V for the prepared
electrolyte film which contains 30 wt % of the ionic liquid. The optimized films have good potential to be used as electrolyte materials for energy storage applications.

to introduce ILs into polymergelelectrolytes. Currently, ILs have received much attention due to their unique properties, such as a wide electrochemical window, high ionic conductivity, non-volatility, non-flammability, small vapor pressure, broad liquid range, and outstanding thermal stability in
