▎ 摘  要

NOVELTY - Preparation of titanium dioxide-graphene composite involves taking potassium chloride as salt template, non-metal phthalocyanine as carbon source and nitrogen source, preparing mixture of graphene and potassium chloride salt by ion-thermal method, using isopropyl titanate to hydrolyze in ethanol, uniformly growing a layer of titanium dioxide on a surface of graphene under the action of hexadecylamine surfactant, centrifuging, water washing, and drying. USE - Preparation of core-shell cavity structure titanium dioxide-graphene composite used as anode material for lithium-ion battery (all claimed). ADVANTAGE - The method enables preparation of core-shell cavity structure titanium dioxide graphene composite with long-cycle stability, high cycle specific capacity, and excellent electrochemical performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1.a core-shell cavity structure titanium dioxide graphene composite; and 2.an application of the titanium dioxide graphene composite as anode material for lithium-ion battery.
