NOVELTY - A cathode material comprises raw materials comprising 80-100 pts. wt. substrate, 2-3 pts. wt. polyimide conductive adhesive, 1-2 pts. wt. graphene, 1-2 pts. wt. carbon black, 0.1-0.2 pt. wt. titanium, 0.1-0.2 pt. wt. platinum, 0.05-0.08 pt. wt. tungsten, 0.02-0.03 pt. wt. molybdenum and 0.1-0.2 pt. wt. lithium. USE - Material is used for forming cathode of graphene battery. ADVANTAGE - The cathode material has improved electroconductivity, and maintains high cathode specific capacity after multiple charging/discharging cycles, by doping conductive graphite with titanium, platinum, tungsten, molybdenum and lithium. The cathode formed using the material provides graphene battery having long life. The cathode material can be mass produced by simple method using economical raw materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the cathode material, which involves (i) adding carbon black, titanium, platinum, tungsten, molybdenum and lithium to the polyimide conductive adhesive, stirring evenly to obtain a mixture, applying the mixture to a surface of the substrate and drying in a vacuum environment in a vacuum glove box to form a primary cathode substrate, (ii) oxidizing graphite into graphite oxide, dispersing the graphite oxide in deionized water and adding a reducing agent to obtain a pre-reduced graphene solution, and (iii) coating a surface of the primary cathode substrate with the pre-reduced graphene solution, irradiating the coated substrate with laser beams and drying.
