Problems solved by technology

[0004] 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 positive plate unable to perform normal electrochemical reactions, which will eventually damage the overall performance of the battery.

Description

technical field [0001] The invention belongs to the field of materials related to chemical power sources, and relates to a lead storage battery containing superconducting material additives. Background technique [0002] Lead-acid batteries are widely used in power, energy storage, electric power, communication and other fields, with various types. The basic components involved in the electrochemical reaction in lead-acid batteries are positive electrode paste, negative electrode paste and electrolyte. Positive electrode paste is an important part that determines the overall capacity and performance of the battery. When preparing positive lead paste, conductive substances such as expanded graphite are generally added to improve the conductivity of the lead paste and increase the utilization rate of active materials. However, the corrosion resistance of the battery is poor, the stability is low, and the self-discharge is large, so the service life of the battery is short. ...
