▎ 摘　　要

NOVELTY - Producing transition metal phosphate-graphene nanocomposite, comprises mixing transition metal (M1) precursor solution and phosphoric acid containing transition metal (M2) precursor solution into graphene or graphene oxide dispersed solution including surfactant. The M1 and M2 are lithium, manganese, cobalt, nickel, iron, titanium or vanadium. USE - The nanocomposite is useful in lithium secondary battery for electric vehicle (all claimed). ADVANTAGE - The nanocomposite has simple producing process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for transition metal phosphate-graphene nanocomposite comprising graphene, and transition metal phosphate formed on the graphene surface.
