▎ 摘　　要

NOVELTY - Producing tungsten trioxide/reduced graphene oxide (RGO) composite cathode material, comprises (i) adding ammonium metatungstate, RGO and dilute hydrochloric acid to diethylene glycol to obtain a mixed solution, and then vibrating and dispersing the mixed solution with an ultrasonic generator, (ii) transferring the mixed solution obtained in the step (i) to a reaction vessel for heating, and then naturally cooling to room temperature, and taking out and filtering the mixed solution and washing many times to obtain a black precursor powder, (iii) drying the black precursor powder obtained in the step (2) to obtain a black powder and (iv) placing the black powder obtained in the step (ii) in a microwave oven for calcination, and naturally lowering the temperature to room temperature to obtain black tungsten trioxide/RGO composite powder. USE - The method is useful for producing tungsten trioxide/reduced graphene oxide composite cathode material (claimed). ADVANTAGE - The method produces composite cathode material with small particle size and uniformity, and which exhibits excellent electrochemical performance.
