▎ 摘　　要

NOVELTY - The preparation method involves (1) dispersing graphene oxide and titanium carbide in water and mixing to form a graphene oxide/titanium carbide mixed dispersion, where the mass ratio of graphene oxide and titanium carbide is (2-4):1, (2) casting the graphene oxide/titanium carbide mixed dispersion onto the substrate to generate a graphene oxide/titanium carbide composite film, (3) immersing the graphene oxide/titanium carbide composite film into a sodium hydroxide gel tank to generate a graphene oxide/titanium carbide composite porous hydrogel film, (4) reducing the graphene oxide/titanium carbide composite porous hydrogel film to generate a graphene/titanium carbide composite porous hydrogel film, and (5) drying the graphene/titanium carbide composite porous hydrogel film to obtain a graphene-titanium carbide composite porous gel film. USE - Preparation method of graphene titanium carbide composite porous gel film used in preparation of electrode materials (all claimed) for energy storage device e.g. lithium-ion battery, sodium ion battery and zinc ion battery. ADVANTAGE - The graphene/titanium carbide composite film has porous structure of graphene oxide gel framework, which can increase the ion diffusion channel and active site in the electrode material and improve the electrochemical performance of the electrode materials. The graphene titanium carbide composite porous gel film has good toughness. DESCRIPTION OF DRAWING(S) - The drawing shows a cyclic voltammetry curve of the graphene/titanium carbide composite porous gel film. (Drawing includes non-English language text)
