Abstract

The invention provides a lead paste for a high-performance lead-acid storage battery. The lead paste comprises a positive lead paste formula and a negative lead paste formula; the lead paste is characterized in that the positive lead paste is prepared from the following components by weight: 1.1kg of antimonous oxide, 0.95kg of stannous mono-sulphate, 1.96kg of graphite, 0.66kg of a polyester staple fiber, 100kg of pure water, 80kg of sulfuric acid, 1,000kg of lead powder and 0.35kg of tetrabasic lead sulphate; and the negative lead paste is prepared from the following components by weight: 202kg of graphite, 1.8kg of lignin, 7kg of barium sulfate, 0.65kg of polyester staple fiber, 2.2kg of humic acid, 110kg of pure water, 78kg of sulfuric acid, 1,000kg of lead powder and 0.23kg of tetrabasic lead sulphate. The tetrabasic lead sulphate is introduced on the basis of the graphite, the polyester staple fiber and the like, so that the active substance in the lead paste is high in strength and small in formation difficulty; after the battery is assembled, the initial capacity of the battery is high; and the cycle lifetime is long.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a high-performance lead-acid battery lead paste. Background technique [0002] The curing of the positive electrode of lead-acid batteries is a key process in battery manufacturing. During the curing process, the chemical and physical structural basis of the active material is established, and the plate obtains mechanical strength, so that the subsequent process operations can be carried out. According to the AOS theory: as the battery cycle progresses, the positive electrode active material repeatedly expands and contracts, and the neck area between the particles becomes smaller, making the contact between the active material particles more and more poor, and the electrical conductivity deteriorates, eventually leading to The active material softens and falls off, the battery capacity is obviously attenuated, and the battery fails. Therefore, improving the charge a...
