▎ 摘　　要

NOVELTY - Lead-carbon battery cathode comprises negative grid and lead paste, including 20-30 pts. wt. lead powder, 10-15 pts. wt. sulfonated graphene, 0.8-1.2 pts. wt. carbon black, 0.5-1 pts. wt. short fiber, 0.5-1.2 pts. wt. barium sulfate, and 1-1.5 pts. wt. additive. The additive is sodium lignosulfonate, humic acid and oak powder. USE - Lead-carbon battery cathode i.e. capacitor-type lead-acid battery of a vehicle. ADVANTAGE - The lead-carbon battery cathode has better capacitance characteristics enhancing instantaneous high current discharge performance of the battery and inhibiting the problem of cathode sulfate, at the same time, reducing the hydrogen evolution potential of battery, can inhibit the water loss of battery and prolong the shelf life of battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparing the lead-carbon battery cathode. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of a lead-carbon battery cathode (Drawing includes non-English language text).
