Problems solved by technology

[0002] Negative plate and negative electrode paste are important factors affecting the performance of lead-acid batteries, but the importance of the negative electrode has always been easily overlooked
The irreversible deposition of lead sulfate on the surface of the negative plate during the discharge process is the main reason for the increase of the internal resistance of the battery, the heating of the battery and the eventual failure of the battery.
Although part of the lead sulfate can be converted into an active substance by charging with a large current, it consumes a lot of energy and is cumbersome to operate
At the same time, the failure of the negative plate will make the active material of the negative plate unable to perform normal electrochemical reactions, which will eventually damage the overall performance of the battery.
