Deep-cycle long-life lead-acid storage battery lead paste for parking, battery thereof and manufacturing process method of battery

Abstract

The invention belongs to the technical field of manufacturing of lead-acid storage batteries for starting, and particularly relates to a deep-cycle long-life lead-acid storage battery lead paste for parking, a battery thereof and a manufacturing process method of battery. The deep-cycle long-life lead-acid storage battery lead paste for parking comprises positive lead paste and negative lead paste, wherein the positive lead paste is prepared from 71-80% of lead powder, 5.8-7.2% of sulfuric acid solution, 10-12% of water, 4-10% of red lead, 0.06-0.25% of antimony trioxide and phosphoric acid in total and 0.07-0.08% of polyester fiber; and the negative lead paste is prepared from 79.5-82% of lead powder, 6.5-6.8% of a sulfuric acid solution, 10-12% of water, 0.8-1.0% of superfine barium sulfate, 0.15-0.25% of Norway A type lignin, 0.3-0.4% of humic acid, 0.2-0.3% of acetylene black and 0.05%-0.06 of polyester fibers. The deep cycle performance of the battery is effectively improved and the cycle service life of the battery is obviously prolonged by optimizing the positive and negative lead paste formulas, performing age hardening and grid surface corrosion film generation treatment on the grid in stages, curing the unformed plate in stages and optimizing the charging formation process parameters.

Description

technical field [0001] The invention belongs to the technical field of manufacturing lead-acid batteries for starting, and in particular relates to a deep-cycle long-life lead-acid battery lead paste for parking, a battery, and a manufacturing process for the battery. Background technique [0002] The lead-acid battery for parking is a subdivision of the starter lead-acid battery. On the one hand, this type of lead-acid battery must meet the needs of the car’s starting function, and on the other hand, it must meet the electronic equipment on the truck when the truck is parked, such as inverter. Therefore, this type of lead-acid battery needs to have high-current starting function and deep cycle performance (power battery function). However, in the actual use process, there are problems of poor deep cycle performance and short service life. Generally, after about 6-7 months of use, the battery capacity decays below 65% of the rated capacity. The main failure modes of this ty...
