NOVELTY - Preparing columnar graphene oxide/tungsten trioxide/sulfur composite material comprises (i) dissolving sodium tungstate dihydrate in aqueous graphene solution, adjusting pH to 2 using hydrochloric acid, adding ammonium sulfate and subjecting to hydrothermal reaction, then freeze drying to obtain three-dimensional columnar graphene oxide/tungsten trioxide material, and (ii) mixing the obtained material and sublimed sulfur, then reacting to obtain final product. USE - The material is useful in the field of chemical batteries. ADVANTAGE - The method: is simple, feasible and is low cost, and the produced material has uniform morphology, high specific surface area and large pore volume, and improves coulomb efficiency of the battery and cycle stability.
