Embodiment 1
[0036] By ultrasonic dispersion method or stirring dispersion method, graphene (1~50 layers) is dissolved in NMP (nitromethylpyrrolidone) solution, forms stable graphene solution (solution concentration 0.01~1mg / mL); In this embodiment , the concentration of graphene in the solution is 0.03mg / mL.
[0037] Use commercial filter paper (medium-speed qualitative filter paper) as the filter medium, filter 300mL graphene solution by vacuum filtration, and repeatedly filter until the black graphene solution becomes colorless, take out the filter paper and dry it at 120°C for 12 hours to obtain graphene / Paper Nanocomposites.
[0038] In the graphene / paper nanocomposite material of this embodiment, graphene accounts for 7.5% by mass of the composite material, and the rest is paper fiber; the composite material is a disc with a radius of 18 mm and a thickness of 200 μm.
[0039] The obtained nanocomposite material was cut into discs (13 mm in diameter) as electrode sheets, Au sheet a...
