Abstract

The invention discloses a preparation method of a sealed high-energy-storage lead-acid storage battery with a quick charging and discharging function. The storage battery mainly comprises a storage battery box body, a plurality of integrated ultra-thin polar plate groups, a circuit connecting piece, an electrolyte and an anti-expansion sleeve. By virtue of the technology, the conventional procedures of processing of the lead-acid storage battery are overturned, and through innovation of a continuous spraying process of fluid lead paste, one-time combination of each polar plate group in a wet soft state can be completed, so that adhesion of lead paste and a partition plate can be reinforced; and the polar plate groups are tightly assembled and plugged into a polar plate cavity in a wet softstate to be subjected to overall curing and drying, so that integration of the polar plate groups is realized, falling off of the lead paste is prevented effectively, the thicknesses of the polar plates and the partition plate are greatly lowered, the polar plate spacing is greatly reduced, lamination of the lead paste and a grid is reinforced, the area of the polar plates and the current collecting grid within the unit space is multiplied, and the energy density and charging and discharging speed of the storage battery are greatly improved.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a preparation method of a fast-charging and discharging sealed high-energy-storage lead-acid battery. Background technique [0002] Lead-acid battery refers to a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the charged state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the discharged state, the main component of the positive and negative electrodes is lead sulfate. Lead storage battery is a battery system invented by Plant in 1859. It has a history of more than 100 years and is the most widely used chemical power source in the world. Although new batteries such as nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries have been introduced and applied in recent years, lead-acid batteries sti...
