NOVELTY - A conductive paste preparation method involves utilizing crystalline flake graphite, concentrated sulfuric acid, glacial acetic acid and peroxide as raw materials, reacting to obtain graphene precursor, calcining the graphene precursor and preparing graphene. The graphene is mixed with organic solvent followed by dispersing mixture of graphene and organic solvent. USE - Method for preparing conductive paste that is utilized for power battery. ADVANTAGE - The method enables preparing conductive paste with high production efficiency and suitability for increasing capacity of battery and reducing internal resistance by increasing addition amount of positive electrode active material at large scale in a simple and convenient manner.
