▎ 摘　　要

NOVELTY - Positive lead paste comprises 70-85 pts. wt. lead powder, 0.5-1.5 pts. wt. tetrabasic lead sulfate crystals, 0.5-1.2 pts. wt. short fibers, 0.1-0.3 pt. wt. graphene, 0.1-0.5 pt. wt. colloidal graphite, 0.01-0.05 pt. wt. cobalt sulfate, 0.01-0.05 pt. wt. stannous sulfate, 0.01-0.1 pt. wt. antimony pentoxide, 5-8 pts. wt. sulfuric acid, and 7-15 pts. wt. deionized water. USE - The lead paste is useful for a silicon-based lead-acid battery and in storage battery processing technology field, especially for a silicon based bipolar lead acid storage battery having a strong PbO2 framework structure, having good conductive ability, but also can be tightly combined with the lead alloy plating layer on the silicon plate, and it is not easy to fall off in the circulation process, so as to improve the large current discharge capability of the lead acid battery and prolong the cycle life. ADVANTAGE - The silicon-based lead-acid battery anode lead paste has excellent conductive ability, and can be tightly combined with the lead alloy plating layer on the silicon plate, and is not easy to fall off in the circulation process, so as to improve the large current discharge capability and prolong the cycle life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the positive lead paste.
