▎ 摘　　要

NOVELTY - Cathode lead paste comprises 100 pts. wt. lead powder, cathode additive and deionized water acid. The cathode additive comprises 0.7-1.5 pts. wt. barium sulfate, 0.1-0.15 pts. wt. graphene, 0.2-0.35 pts. wt. acetylene black, 0.1-0.15 pts. wt. lignin, 0.2-0.3 pts. wt. humic acid, 0.1-0.125 pts. wt. sodium polyaspartate, 0.08-0.12 pts. wt. polyester staple fiber, 0.01 pts. wt. oxide, 0.25 pts. wt. carboxymethylcellulose and 0.01 pts. wt. vanillin. USE - The cathode lead paste is useful for lead-acid battery (claimed). ADVANTAGE - The cathode lead lead-acid battery has excellent water absorption characteristics, and large current discharge performance, and improved hydrogen evolution over potential of the cathode, inhibits hydrogen evolution, and battery life, and prevents the negative plate from foaming and separating from the plate grid, improves the charging receiving ability of the active substance, and reduces the attenuation of the low temperature capacity of the cathode in the circulation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of the cathode lead lead-acid battery.
