NOVELTY - A lithium ion battery cathode paste preparing method involves mixing 32-43% solvent and 1-5% oil binding agent to obtain mixture A. The mixture A is added with 1-1.5% graphene and the resulting mixture is stirred under 25-40 degrees C for 2-4 hours to obtain mixture B. The mixture B is added with 55-65% nickel -cobalt lithium aluminate powder and the obtained mixture is stirred for 2-4 hours followed by adding oxalic acid and adjusting pH to 8-9.5. USE - Method for preparing lithium ion battery cathode paste that is utilized in lithium ion battery (claimed) of hybrid vehicle, telecommunications network and space and defense equipment. ADVANTAGE - The method enables preparing lithium ion battery cathode paste with high power, high safety performance and excellent charge-discharge cycle life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use of lithium ion battery cathode paste in lithium ion battery.
