▎ 摘　　要

NOVELTY - Spherical nano graphene conductive paste comprises deionized water, additive powder and spherical nano-graphene in a ratio of 1:1:1, where amount of deionized water is 80-90g, and spherical nano-graphene is 2-6g. The additive powder comprises 2-3g dispersant, 8-10g solvent, and 3-5g adhesive. USE - Spherical nano graphene conductive paste used in lead-acid battery. ADVANTAGE - The spherical nano graphene conductive paste has reasonable structure, more market and special benefit, increases service life of energy storage in lead-niobium by 5 times, increases service life of energy storage in lithium battery anode and cathode material by 8 times, and repairs various battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a spherical nano graphene conductive paste, which involves: (A) dispersing spherical nano-graphene in a solvent ultrasonically to obtain a spherical nano-graphene dispersion; and (B) adding dopants to spherical nano-graphene solution, putting it in a water reactor, stirring and diluting it with distilled water to the required ratio, and then stirring it uniformly to obtain final product.
