Description

TECHNICAL FIELD

[0002] The performance of the battery substrate directly affects the overall efficiency and service life of the battery. After the battery substrate (i.e. the pole plate) is formed, it needs to react with sulfuric acid to achieve energy storage and release. Since the substrate has a certain thickness, the effective contact between the lead dioxide inside and the sulfuric acid becomes the key to improving the reaction rate. Therefore, the battery substrate needs to further improve the porosity.

[0003] In the prior art, the raw materials are generally added to the stirring kettle for uniform stirring. In order to improve the porosity, a certain amount of perborate is added to the stirring kettle through the feed port.
