NOVELTY - A lithium-ion battery cathode material producing method involves adding graphene, polyethyleneimine, polyvinyl alcohol and ethyl acetate to aqueous ethyl alcohol solution. The obtained mixture is heated and filtered to obtain solid mixture and solvent is removed under vacuum to obtain modified graphene. Modified graphene, butyl titanate, ammonium molybdate and polyethylene glycol are added to a reaction kettle and heated to obtain intermediate material. The intermediate material is immersed in deionized water for 3-5 hours, filtered and dried to obtain finished product. USE - Method for producing lithium-ion battery cathode material. ADVANTAGE - The method enables producing the lithium-ion battery cathode material with improved capacity and stability. DETAILED DESCRIPTION - A lithium-ion battery cathode material producing method involves adding 10-20 pts. wt. graphene, 5-10 pts. wt. polyethyleneimine, 2-5 pts. wt. polyvinyl alcohol and 5-10 pts. wt. ethyl acetate to 80-100 pts. wt. aqueous ethyl alcohol solution. The obtained mixture is heated for 20-30 minutes and filtered to obtain solid mixture and solvent is removed under vacuum to obtain modified graphene. 10-20 pts. wt. modified graphene, 2-3 pts. wt. butyl titanate, 1-4 pts. wt. ammonium molybdate and 1-3 pts. wt. polyethylene glycol are added to a reaction kettle and heated for 20-30 minutes to obtain intermediate material. The intermediate material is immersed in deionized water for 3-5 hours, filtered and dried to obtain finished product.
