Electrochemical capacitors (ECs) are energy storage devices with high power density and high efficiency, but their liquid electrolytes can contain environmentally unfriendly compounds and are vulnerable to leakage. Ionic liquids (ILs) provide non-volatile ionic conductivity in flexible polymer electrolytes, which can alleviate these issues. The ILs 1-ethyl-3-methylimidazolium hydrogen sulfate (EMIHSO4) and 1-methylimidazolium hydrogen sulfate (MIHSO4) were combined into a binary mixture with a deeply depressed melting point, and a phase diagram was constructed after thermal analysis. On ruthenium dioxide electrodes, 70-30 wt% EMI-MIHSO4 showed an increase in capacitance of about 75% over that of neat EMIHSO4, demonstrating its proton activity. The binary IL mixture was incorporated into a polyvinyl pyrrolidone polymer matrix to form polymer electrolytes that showed good electrochemical performance and rate capability under electrochemical impedance spectroscopy and cyclic voltammetry. On ruthenium dioxide electrodes, the PVP-EMI-MIHSO4 electrolyte showed a 30% improvement in capacitance over PVP-EMIHSO4.
