Problems solved by technology

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 capacity low 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 environment

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Such as Figure 1 ~ Figure 4 As shown, the lead-acid battery electrode grid 1 provided by the embodiment of the present invention includes a lead substrate (i.e. a rolled lead strip), on which a number of evenly distributed mesh holes 11 are punched, and a frame 12 is respectively arranged around the substrate. , one of the frames 12 is provided with an outwardly protruding tab 13 .

[0025] After the electrode grid 1 of the present invention is used on a lead-acid battery, the mesh 11 of the electrode grid 1 is filled with active electrolytic substances, and the current generated by the ox...

Abstract

The invention relates to an electrode grid of a lead acid battery. The electrode grid is characterized in that: the grid comprises a lead substrate; the substrate is punched with a plurality of meshes which distribute uniformly; each side of the substrate is provided with a frame; and one frame is provided with a tab which bulges outwardly. When the electrode grid of the present invention is used on the lead acid battery, and active electrolytic substances are filled in the meshes of the electrode grid, a current which is generated when the active electrolytic substances are subjected to a redox reaction is transmitted out through the tab to realize power supply. Rolled lead strips are used, the tissue density is substantially higher than the density of cast grids with loosened tissue structures, so the electrode grid of the present invention which is more corrosion resistant allows the service life of the battery to be prolonged. When conductive properties are guaranteed, ribs of the grid of the present invention can be finer than the ribs of the cast grids, so the lead consumption amount can be saved. The invention also provides a manufacturing process of the electrode grid of the lead acid battery, and the process has the advantages of energy saving, environmental protection, high production efficiency and grid consumption saving.

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...
