▎ 摘　　要

NOVELTY - Graphene/tannin furfuryl alcohol resin-derived carbon anode material comprises graphene and tannin furfuryl alcohol resin-derived carbon. The graphene is coated on the surface of the tannin furfuryl alcohol resin-derived carbon. The graphene/tannin furfuryl alcohol resin-derived carbon anode material is obtained by pyrolytic carbonization of tannin furfuryl alcohol resin-derived carbon, graphene oxide, and surfactant. The tannin furfuryl alcohol resin-derived carbon is obtained by carbonizing the tannin furfuryl alcohol resin prepared by tannin extract, furfuryl alcohol and a curing agent. USE - Graphene/tannin furfuryl alcohol resin-derived carbon anode material used in lithium ion batteries or sodium ion batteries (claimed). ADVANTAGE - The graphene/tannin furfuryl alcohol resin-derived carbon anode material has environmental protection and wide range of raw material sources and renewable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene/tannin furfuryl alcohol resin-derived carbon anode material, which involves: (A) using tannin furfuryl alcohol resin as a precursor, it is pre-carbonized at a temperature of 400-600 degrees C under a gas atmosphere, cooling, after grinding, and heating at 900-1200 degrees C under a gas atmosphere for heat Decarbonization to obtain carbon derived from tannin furfuryl alcohol resin; (B) dispersing obtained tannin furfuryl alcohol resin-derived carbon and graphene oxide in a solvent to obtain a suspension; and (C) adding a surfactant to the suspension, mixing uniformly, filtering and drying, and heating under a gas atmosphere and performing pyrolysis and carbonization at a temperature of 900-1200 degrees C to obtain graphene/tannin furfuryl alcohol resin-derived carbon anode material.
