  • Patent number: 10930441
    Abstract: In this patent, a high energy and power density supercapacitor was invented. A coin cell with supercapacitor includes a spring lamination, a working electrode, a counter electrode, a separator, and an Organic electrolyte. The working and counter electrodes were Activated carbon/N-doping porous graphene/binder coated on Aluminum substrate. The separator was from Nippon Kodoshi Corporation. The Organic electrolyte was 1M TEABF4/PC. The method of producing N-doping porous graphene included the following steps: Step 1: Graphite oxide (GO) was transferred into the furnace. Step 2: Inject 50 c.c./min gas flow of Nitrous oxides for one hour. Step 3: Intensify 40 Celsius degrees/min to 900 Celsius degrees and after holding for one hour, lower the temperature naturally to the room temperature, it can be prepared into N-doping porous graphene. In this patent, the capacitance of the supercapacitor is 122 F/g and the power density is 31 kW/Kg.

  • Patent number: 10872735
    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: S1: Graphite oxide is quickly transferred into the furnace, which had been held at 300° C. and the porous graphene can be produced. S2: The porous graphene and red phosphorus are put together in the evacuated tube furnace and heated to 700° C. for 1 hr. S3: 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.
