NOVELTY - The production method of magnesium oxide-zinc oxide-graphene composite material involves dispersing a mixture of zinc nitrate hexahydrate and magnesium chloride hexahydrate in an oxidized graphene solution, adjusting the pH of aqueous ammonia to 11, transferring the mixture to a stainless steel reaction kettle, reacting at 160-200 degrees C for 8-12 hours, naturally cooling to room temperature, washing with deionized water and vacuum-drying at 50-70 degrees C for 10-14 hours. The weight ratio of zinc nitrate hexahydrate and magnesium chloride hexahydrate in the mixture is (7-9):1. USE - Production of magnesium oxide-zinc oxide-graphene composite material used for battery (claimed). ADVANTAGE - ADVANTAGE C; The method enables the production of composite material with excellent charge-discharge cycle performance. DETAILED DESCRIPTION - The production method of magnesium oxide-zinc oxide-graphene composite material involves dispersing a mixture of zinc nitrate hexahydrate and magnesium chloride hexahydrate in an oxidized graphene solution, adjusting the pH of aqueous ammonia to 11, transferring the mixture to a stainless steel reaction kettle, reacting at 160-200 degrees C for 8-12 hours, naturally cooling to room temperature, washing with deionized water and vacuum-drying at 50-70 degrees C for 10-14 hours. The weight of the mixture is equal to the weight of the graphene oxide. The weight ratio of zinc nitrate hexahydrate and magnesium chloride hexahydrate in the mixture is (7-9):1. An INDEPENDENT CLAIM is included for the application of magnesium oxide-zinc oxide-graphene composite material in battery.
