NOVELTY - A graphene material modifying method involves adding graphene to a sodium dodecyl benzene sulfonate solution in a concentration of 0.01-0.03 mol/L to obtain a mixture. The mixture is subjected to ultrasonic treatment at 100-500 rpm for 5-10 minutes, followed by reacting in a water bath for 48-24 hours and spray-drying. The graphene sodium dodecyl benzene sulfonate is added to soluble lead salt solution in a concentration of 10-20 mg/L to. The mixed solution is subjected to ultrasonic treatment at 20-240 rpm for 0.5-5 hours and spray-dried. USE - Method for modifying graphene material that is utilized for a lead-carbon battery. ADVANTAGE - The method enables modifying the graphene material with improved compatibility and durability of the battery and reduced interfacial resistance. DETAILED DESCRIPTION - A graphene material modifying method involves adding graphene to a sodium dodecyl benzene sulfonate solution in a concentration of 0.01-0.03 mol/L to obtain a mixture. The mixture is subjected to ultrasonic treatment at 100-500 rpm for 5-10 minutes, followed by reacting in water bath for 48-24 hours and spray-drying to obtain surface adsorption with graphene sodium dodecyl benzene sulfonate having a mass ratio of 0.5-1.2%. The graphene sodium dodecyl benzene sulfonate is added to soluble lead salt solution in a concentration of 10-20 mg/L to obtain mixed solution. The mixed solution is subjected to ultrasonic treatment at 20-240 rpm for 0.5-5 hours and spray-dried to obtain a final product, where the graphene and sodium dodecyl benzene sulfonate solution having a mass ratio of 0.5-1.2%.
