Supercapacitor activated carbon is a new type of high-adsorption activated carbon that discharges electricity by moving electrons between conductors (without relying on a chemical reaction) during discharge, thereby providing power to the device. Mainly used for supercapacitors (also called double layer capacitors, electrochemical capacitors), with large specific surface area, good electrochemical performance, high capacity, etc., also in electric vehicles, hybrid vehicles, power tools, electric toys, railway systems , Power systems and other wide applications have been applied.
