NOVELTY - A nickel-cobalt oxide/graphene composite material comprises nickel cobalt oxide and graphite, where the nickel cobalt oxide is nickel cobaltite. USE - Nickel-cobalt oxide/graphene composite material. ADVANTAGE - The material is formed with a laminated structure, in short time. The material is inexpensive and energy-saving. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing nickel-cobalt oxide/graphene composite material, which involves mixing bivalent cobalt salt and divalent nickel salt at mol ratio of 2:1 in de-ionized water or organic solvent, adding graphite oxide to the mixture, adding alkaline regulator to the obtained mixture to regulate pH value to 8-10, pre-heating the mixture at temperature of 70-90 degrees C for 8-32 hours to obtain a mixed solution, sealing the mixed solution and raising temperature of the solution to 140-200 degrees C, cooling the solution for 1-24 hours to collect a solid product, and washing and drying the product to obtain a finished product.
