Description

technical field [0001] The invention belongs to the field of materials related to chemical power sources, and in particular relates to a positive electrode paste formula that can be used for lead storage batteries. 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...
