Capacitive Behavior of NiO in Ionic Liquid

Ionic liquids are characterized by non-volatility, non-flammability and relatively high ionic conductivity, which make them attractive as an electrolyte for electrochemical capacitors. Most studies on ionic liquids as electrolyte have focused on carbon electrodes and studies using oxide electrodes are limited. Recently, the capacitive behavior of nickel-based rare-earth oxide in ionic liquids was reported. Promising results were obtained; a wide potential window of 2 V and specific capacitance of 357 F g in BMI-PF6. In this work, the electrochemical properties of NiO in several different ionic liquids were studied in an attempt to understand the (pseudo)capacitive behavior.
