NOVELTY - Preparing rubber-peeled graphene composite electrode material involves: (a) removing graphite sheet, adding rubber matrix and graphite raw material to internal mixer, and after 3-20 minutes of mixing, transferring the mixture to double-roller open mill for kneading for 10-60 minutes to obtain 4-45% composite rubber block containing graphene or graphene oxide; (b) mixing energy storage active substances, adding composite rubber block to calendering machine, adding 5-30 ml energy storage active powder and dioctyl phthalate, and kneading the mixture for 10-30 minutes; (c) carbonizing composite rubber, placing in a crucible, capping, placing in a heating device, and calcining at 500-1000 degrees C for 10-50 minutes to obtain energy storage active substance-graphene carbonized foam carbide; and (d) grinding energy storage active substance-graphene carbonized foam carbide and passing through 200-350 mesh sieve to obtain an energy storage active material-graphene conductive agent active powder. USE - The method is useful for preparing rubber-peeled graphene composite electrode material used in assembling graphene-bonded lithium ion battery (all claimed). ADVANTAGE - The rubber-peeled graphene composite electrode material can greatly improve the high-rate charging and discharging performance of the conventional lithium ion battery and the charging speed. DETAILED DESCRIPTION - Preparing rubber-peeled graphene composite electrode material involves: (a) removing graphite sheet, adding rubber matrix and graphite raw material to internal mixer, and after 3-20 minutes of mixing, transferring the mixture to double-roller open mill for kneading for 10-60 minutes to obtain 4-45% composite rubber block containing graphene or graphene oxide, where the mass ratio of rubber matrix:graphite raw material is 100:5-70; (b) mixing energy storage active substances, adding composite rubber block to calendering machine, adding 5-30 ml energy storage active powder and dioctyl phthalate, and kneading the mixture for 10-30 minutes to form graphene-storage active material-the rubber composite film, where the mass of the energy storage active material is 3-9 times the mass of graphene or graphene oxide contained in the composite rubber block; (c) carbonizing composite rubber, placing in a crucible, capping, placing in a heating device, and calcining at 500-1000 degrees C for 10-50 minutes to obtain energy storage active substance-graphene carbonized foam carbide; and (d) grinding energy storage active substance-graphene carbonized foam carbide and passing through 200-350 mesh sieve to obtain an energy storage active material-graphene conductive agent active powder, that is a composite electrode material.
