Technical Field
The invention belongs to the technical field of storage batteries, and particularly relates to a positive electrode formula suitable for a lead-acid energy storage battery.
Background
When the lead-acid storage battery is recycled, one of the main failure modes is softening and falling of the positive lead paste, and the essence is the deterioration of lead paste crystals, so that the lead paste is softened and falls, and the capacity of the battery is reduced and fails. Therefore, how to improve the mechanical strength of the positive lead plaster and delay the deterioration rate of the positive lead plaster crystal in the recycling process is the key for improving the cycle life of the lead-acid storage battery.
In order to improve and enhance various properties of the storage battery, additives are often added into the lead plaster formula. The additives are generally classified into conductive additives, non-conductive additives, chemically active additives, and the like. Experimental results prove that the small-particle carbon material is added into the negative lead paste according to a certain proportion, the conductivity of the negative lead paste can be obviously improved, and the small-particle carbon material has obvious effects of improving the charge acceptance of the battery and resisting the sulfation tendency of the negative lead paste.
However, the use of carbon fibers as an additive for positive electrode lead paste is relatively rare. Mainly because sulfation mainly occurs in the negative electrode, the charge acceptance of the battery is mainly limited by the negative electrode due to the specific surface area of the active substance, the research on adding the carbon material into the positive electrode lead paste is not deep enough, the application markets such as power and energy storage put forward higher requirements on the cycle performance of the lead-acid storage battery, and after the problems of the charge acceptance of the negative electrode and the sulfation are basically solved, how to improve the softening resistance of the positive electrode lead paste in the cycle use process is an increasingly important subject.

0.8-1.0kg of sulfate;
3.0-3.5kg of antimony oxide;
