Embodiment Construction

[0028] Such as figure 1 , figure 2 , image 3 Shown. The grid of a lead-acid battery of the present invention includes a grid framework 2 and a lead paste 3 attached on the surface. The thickness of the grid skeleton 2 is 0.3~2mm, and the surface 1 is a surface with a roughness of 3.2~12.6. The roughness of the surface is formed by the rolling method, stamping method, sandblasting method, and sanding method. 12.6 surface. The rough surface 1 of the grid frame is coated with lead paste. The thickness of the grid can be thinner than 1 mm.

[0029] The method for forming and surface treatment of a lead-acid battery grid of the present invention includes the following steps:

[0030] ①Preparation of lead alloy: Pre-refined lead alloy is prepared according to the standard, which is the same as the existing method;

[0031] ②Melting the lead alloy: Put the pre-finished lead alloy into the lead melting pot and heat it to 350~500℃ until all the pre-finished lead alloy is melted, which ...

Abstract

The title of the present invention is a lead-acid storage battery grid and its forming surface treatment method. It belongs to the technical field of storage batteries. It mainly solves the problem that the existing perforated grid has poor adhesion of the lead paste, and the paste is easy to drop during the production process, which affects the performance of the battery. Its main features include: ①preparation of lead alloy; ②melting lead alloy; ③casting lead plate; ④pressing lead belt; Surface roughening treatment: roughen the surface of the above continuous grid skeleton structure, the roughness is 3.2~12.6, and the grid is completed; ⑦ plate filling: fill the above grid skeleton with lead paste, The board is finished. The invention has the characteristics of improving the bonding force between the perforated grid and the lead paste, and the thickness of the grid can be less than 1 mm, and is especially suitable for manufacturing the perforated grid of high-power batteries.

Description

Technical field [0001] The invention belongs to the technical field of storage batteries. Specifically, it relates to a lead-acid battery grid and a molding surface treatment method thereof. Background technique [0002] Traditional lead-acid battery grids are produced by gravity casting, with mature technology, but they have the disadvantages of heavy weight, low production efficiency, low corrosion resistance, and large deviations in process quality control. Later, a stretched mesh grid appeared, which was light in weight, high in production efficiency, and strong in corrosion resistance. However, because there was no left and right frame, it had the disadvantage that the grid should grow and short circuit and cause the battery to end early. The punching grid produced by machine cold rolling has the characteristics of corrosion resistance, light weight, long life, simple production process, stable quality, and convenient management. The grid can be made thinner and more unifor...
