▎ 摘　　要

NOVELTY - The battery has a battery shell provided with a positive pole plate grid and a negative pole plate grid. A separator is placed between anode and cathode slab lattices and fixed with an electrolyte in the shell. The positive pole plate grid is coated with anode lead paste during curing and drying processes to obtain graphene anode paste. The negative pole plate grid is coated with cathode lead paste during curing and drying to obtain graphene cathode paste. The anode lead paste and the cathode lead paste are provided with 0.02-3 percent high-quality graphene. USE - Lead-acid battery. ADVANTAGE - The battery ensures that a graphene material can be quickly charged and discharged in an effective manner. The battery has high capacity and prolonged service life.
