Abstract

The invention provides a lead plaster composition for manufacturing a positive plate of a lead-acid storage battery, which, by weight percentage, comprises 3% to 10% of sulfuric acid, 10% to 15% of water, 0.05% to 0.15% of short fibers, 0.01% to 0.2% of graphite powder, 0.001% to 0.1% of polytetrafluoroethylene emulsion, and the balance lead powder. The lead powder has electrical conductivity and can improve electrical conductivity of active substances of the lead-acid storage battery so as to improve charge acceptance of the lead-acid storage battery, and the polytetrafluoroethylene emulsion can enhance fastness of organizational structures of the active substances and enable the graphite powder to enhance the electrical conductivity of the active substances preferably so as to improve the charge acceptance of the lead-acid storage battery further. The invention provides the positive plate of the lead-acid storage battery manufactured by the lead plaster composition and the lead-acid storage battery which is assembled by the positive plate of the lead-acid storage battery.
