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.

Conductive carbon adhesive is an active technology researched in the world, and its application is quite wide, such as liquid crystal display (TFTLCD), organic light emitting diode (OLED), radio frequency identification system (RFID), antenna, solar cell, sensing and electronic components for devices. Since the two-dimensional carbon material used for the conductive carbon adhesive is easily stacked and agglomerated in the polymer, the present invention adds nano-fillers to the carbon material to prepare a three-dimensional conductive carbon adhesive to prevent carbon material agglomeration.
