Abstract

The invention relates to a method for making a lead-acid battery pole plate, which is characterized by comprising the following steps: adopting a foamy carbon with a three-dimensional structure as a skeleton, and electroplating lead or lead alloy on the skeleton to obtain a grid; coating active materials on the grid, and solidifying and drying the grid; and casting a lead or lead-alloy frame on the grid subjected to solidification and drying to obtain the lead-acid battery pole plate. The lead-acid battery pole plate is environment-friendly, can greatly reduce the lead consumption and significantly reduce the weight of the battery pole plate, and can three-dimensionally contact the active materials so as to make the current and potential distributed more uniformly on the battery pole plate, thereby reducing the electrochemical polarization and polarization resistance on the surface of the battery, facilitating the transformation of the active materials, and improving the utilization ratio and specific energy of the active materials. The lead-acid battery pole plate prepared by the method adopts the lead or lead-alloy frame, can facilitate process after-treatment, and has good process processability.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a method for manufacturing a lead-acid battery pole plate. Background technique [0002] At present, lead-acid batteries are the most used batteries in the world, but the traditional battery plates still use cast lead grids. This battery plate accounts for about 70% of the weight of the entire battery. At the same time, it consumes a lot of lead resources and pollutes the environment. . SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a method for producing a lead-acid battery pole plate which reduces the weight of the battery, reduces the consumption of lead and has a uniform current distribution. [0004] In order to solve the technical problem proposed by the present invention, the technical scheme adopted is: [0005] A method for making a lead-acid battery electrode plate, the difference is that: taking a foam ...
