Beschreibung
Zusammenfassung:	A method for preparing biomass graphene by using cellulose as a raw material includes preparing a catalyst solution, carrying out ionic coordination and high-temperature deoxidization on cellulose and a catalyst so as to obtain a precursor, carrying out thermal treatment and pre-carbonization, and carrying out acid treatment and drying to obtain the graphene. The graphene is uniform in morphology with a single-layer or multi-layer two-dimensional layered structure having a dimension of 0.5 μm to 2 μm, and an electric conductivity of 25000 S/m to 45000 S/m. The graphene can be applied to electrode materials of super capacitors and lithium ion batteries, and can also be added to resin and rubber as an additive so as to improve physical properties of the resin and the rubber.
