What is a supercapacitor electrode?
What is a supercapacitor electrode? Supercapacitor electrodes are generally thin coatings applied and electrically connected to a conductive, metallic current collector. Electrodes must have good conductivity, high temperature stability, long-term chemical stability (inertness), high corrosion resistance and high surface areas per unit volume and mass. Do supercapacitors have electrolyte? There are currently three types of electrolyte employed in supercapacitors: aqueous electrolyte, organic electrolyte, and ionic liquids [26]. However, aqueous electrolytes have a narrow voltage window of 1.23 V (due to the thermodynamic decomposition of water) [82], much smaller than those of organic electrolytes.
