Technical Field

Background
In the long-term use process of the existing lead-acid storage battery, a large amount of sulfate is formed on the surface of a polar plate, so that the chemical reaction of the internal structure of the polar plate is hindered, the performance of the storage battery is rapidly reduced, abnormal conditions such as floating charge or poor discharge occur, and the storage battery is finally disabled.
