▎ 摘  要

NOVELTY - Cathode material prepared by coke without graphitization comprises 30-40 wt.% asphalt raw material, 5-8 wt.% organic solvent, 1-2 wt.% catalyst, 1-2 wt.% surfactant, 3-6 wt.% graphene and wrapping raw materials (remaining amount), where the organic solvent comprises a mixture of organic solutions and metal salts. The catalyst comprises soluble iron, cobalt, nickel acetate, nitrate, chloride, vanadium, titanium, gold, silver and/or lithium. The wrapping raw material comprises coal tar and/or coal tar pitch. USE - The cathode material is useful for preparing lithium-ion battery. ADVANTAGE - The cathode material: is prepared by coke without graphitization; is mixed by asphalt raw material with organic solvent, catalyst surfactant graphene, and graphene; utilizes inert gas to carbonize without graphitizing manufacturing artificial graphite technology; has low product cost; and solves the problems of graphitization is required, and a high temperature environment needs to be built resulting in waste of resources. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the cathode material prepared by coke without graphitization.
