Abstract
A high volumetric energy and power density supercapacitor is provided. This supercapacitor includes a coin cell, a spring lamination, a working electrode, a counter electrode, a separator, and an ionic liquid electrolyte. The working and counter electrodes are N—P doping porous graphene coated on Al substrate. The ionic liquid electrolyte is EMI-FSI. The method of producing N—P doping porous graphene includes following steps: S: Graphite oxide is quickly transferred into the furnace, which had been held at 300° C. and the porous graphene can be produced. S: The porous graphene and red phosphorus are put together in the evacuated tube furnace and heated to 700° C. for 1 hr. S: Heated to 800° C. for 30 min in a mixed argon and ammoniac atmosphere and then the N—P doping porous graphene can be made. The capacitance of the supercapacitor is 105 F/g and the volumetric power density is 1.19 kW/L.
