Lead-acid battery electrode grid and its manufacturing process

Abstract

A lead-acid storage battery electrode grid, which includes a lead substrate, a number of uniformly distributed mesh holes are punched on the substrate, a frame is respectively arranged around the substrate, and an outwardly protruding tab is provided on one of the frames. After the electrode grid of the present invention is used on a lead-acid battery, the mesh of the electrode grid is filled with active electrolytic substances, and the current generated by the oxidation-reduction reaction of the active electrolytic substances is transmitted through the tabs to achieve the purpose of power supply; the electrode of the present invention The grid uses rolled lead strips, the structure density is much higher than that of the cast grid with loose structure, which is more corrosion-resistant and effectively prolongs the service life of the battery; under the condition of ensuring the electrical conductivity, the grid ribs of the present invention can be compared with the cast grid It is thinner and saves lead consumption of the grid. The invention also provides a manufacturing process of the lead-acid storage battery electrode grid, which has the advantages of energy saving, environmental protection, high production efficiency and saving grid consumption.

Description

technical field [0001] The invention belongs to the technical field of lead-acid batteries, in particular to a lead-acid battery electrode grid and a manufacturing process thereof. Background technique [0002] At present, the electrode grids of lead-acid batteries are still manufactured by the traditional casting process, specifically: the prepared lead alloy is made into lead ingots through the first melting of lead, and then through the second melting, the alloy is used solution for casting. The weight of the electrode grid made by this casting process accounts for half of the weight of the entire battery plate, and it takes up a lot of space in the battery, which makes it impossible to fill more active electrolytes, making the battery low in capacity and unable to achieve high rates. Requirements for charging and discharging; In addition, the casting process is used to produce electrode grids, which has low production efficiency, wastes energy, and pollutes the environm...
