Organic mixed super capacitor

The invention relates to an organic hybrid supercapacitor which consists of a positive electrode, a negative electrode, a diaphragm which is arranged between the positive electrode and the negative electrode, and an organic electrolyte; the positive electrode adopts a lithium-ion intercalation compound, the negative electrode adopts the mixture of hard carbon and porous carbon material, and the electrolyte adopts an organic solvent containing lithium ions. The prepared supercapacitor has high energy density (45-80Wh/Kg) and high power density (more than 4,500W/Kg), and can be widely applied in electric vehicles, electric tools, solar energy storage, wind energy storage and other fields.
