NOVELTY - Composite nanowire of transition metal oxide and graphene is selected from manganese oxide and (tin(IV) oxide), where diameter of composite nanometer wire is 100-500 nanometer. USE - Composite nanowire of transition metal oxide and graphene for energy storage for lithium ion battery (all claimed). ADVANTAGE - The composite nanowire of transition metal oxide and graphene has good conductivity and mechanical performance and excellent storage performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composite nanowire of transition metal oxide and graphene, which involves: (A) selecting transition metal oxide from group consisting of manganese oxide and (tin(IV) oxide); (B) providing 0.5-2 milligram/milliliter polyvinylpyrrolidone to solution and stirring to obtain mixed solution; (C) adding mixed solution in manganese and tin soluble salt; (D) stirring uniformly to form electrospinning solution; (E) treating electrospinning solution to form nanowire; and (F) calcining wire in reducing atmosphere to obtain desired product.
