Method for preparing ultrahigh-power graphite electrode from graphene
The invention relates to the technical field of electrode preparation, and concretely relates to a method for preparing an ultrahigh-power graphite electrode from graphene. Needlelike petroleum coke taken as aggregate and powder materials comprising graphene powder, ultrahigh-power graphite powder, carbon black and carbon fibers undergo solvent dispersion, high-temperature hot press molding and high-temperature purification treatment at the temperature of 3200 DEG C at most to form microcrystalline artificial graphite. The physicochemical properties of the high-power graphite electrode are enhanced. The method has the advantages of reasonable raw material selection, scientific preparation process and the like, and the ultrahigh-power graphite electrode with excellent physical and chemicalproperties is produced by using the method and the materials. The product percent of pass can be increased, the characteristics of graphene, carbon black, carbon fibers and other materials are fully utilized, the medium-temperature coal pitch is easy to graphitize in the graphitization process, and the physicochemical indexes of the final product can be fully met.
