Embodiment Construction

[0026] The method for continuously producing electric vehicle battery pole plates of the present invention comprises the following steps:

[0027] (1) The lead strip made of lead-calcium alloy is punched to obtain the substrate, and the substrate is a planar plate with grid-like ribs; the lead-calcium alloy can be low-calcium and high-tin-lead alloy. see figure 1 , Picture 1-1 and Figure 1-2 .

[0028] (2) The substrate is then shaped and roughened by a deformation mold; see figure 2 , diagram 2-1 and Figure 2-2 .

[0029] (3) The active material is then coated on both sides of the substrate shaped and roughened in (2), respectively, to form a grid. see image 3 , Figure 3-1 and Figure 3-2 .

[0030] Among them, the thickness of the substrate in (1) above is shaped and roughened by the deformation mold so that the thickness of the substrate in (2) is doubled while the weight remains unchanged. Dedicated deformation dies (for example by extrusion). And the s...

Abstract

The invention discloses a method for continuously producing an electric vehicle storage battery pole plate. The method comprises the following steps: punching a lead belt made by using a lead-calcium alloy to obtain a substrate, and shaping and napping the substrate by a deformation die; and coating the surfaces at two sides of the substrate with an active substance to make a grid. The grid has a large amount of vertical ribs and a small amount of transverse ribs, is in favor of heavy current discharge and the increase of the charging reception efficiency of the pole plate, so the polarization of the pole plate is reduced. The method has the advantages of streamline continuous production, saving of a large amount of people and energy consumption, production efficiency improvement and production cost reduction.

Description

technical field [0001] The invention discloses a method for continuously producing battery pole plates of electric vehicles, and relates to the technical field of lead-acid batteries. Background technique [0002] Lead-acid batteries have a history of nearly 150 years since they were invented in 1860. The products are widely used in various fields of human society due to their mature technology and stable quality. Electric vehicle lead-acid battery is a product developed in China in the past 15 years. The product has mature technology and stable quality. However, the main material of the positive electrode of this product is lead-antimony-cadmium alloy, which is very polluting. The state stipulates that the production of lead-antimony-cadmium alloy batteries should be stopped by the end of 2013. The product requires a lot of labor and energy consumption, low production capacity, and low specific energy is a shortcoming of this product. Therefore, how to improve the specific ...
