▎ 摘　　要

NOVELTY - The material comprises graphene placed in an active material. The graphene and graphene oxide are mixed with amide group. USE - Cathode active material for a lithium ion capacitor (claimed). ADVANTAGE - The material processes the graphene oxide as urea, so that the graphene oxide can be utilized as active material, so that battery energy density is not victimized and electrochemical characteristic of a lithium ion capacitor can be improved in a better manner, thus prolonging service life of the lithium ion capacitor. The material improves production efficiency of a graphene base lithium ion capacitor electrode by utilizing polyacrylic acid (PAA) binder. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium ion capacitor cathode active material manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows photographic, schematic and graphical views of a cathode active material.
