NOVELTY - A three-dimensional nickel molybdate-graphene composite nano material synthesizing method involves adding a certain amount of polyvinylpyrrolidone, nickel source and molybdenum source to deionized water and stirring to obtain a solution A, dispersing a certain amount of graphene in deionized water for 10-20 minutes to obtain a solution B, pouring the solution B into the solution A, after ultrasonication for 10-20 minutes obtaining the precursor solution, placing the precursor solution and the pre-treated foamed nickel in the reaction kettle, carrying out the reaction at 100-200 degrees C for 4-8 hours, taking out, washing and drying to obtain the finished product. USE - Method for synthesizing three-dimensional nickel molybdate-graphene composite nano material for nickel-zinc battery. ADVANTAGE - The method enables synthesizing three-dimensional nickel molybdate-graphene composite nano material with high capacity utilization rate, better circulation stability, capacity retention rate of 85.4%, in simple synthesis method.
