Abstract

The invention discloses a capacity rapid recovery method for a lead-acid storage battery, and the method comprises the following steps: S1, preparing raw materials of a function repair solution, including a sulfuric acid electrolyte, sodium sulfate, isoascorbic acid, 2-acrylamide-2-methylpropanesulfonic acid and tetrabutylammonium chloride; S2, mixing sodium sulfate, tetrabutylammonium chloride and the sulfuric acid electrolyte to obtain a repair liquid base material, adding isoascorbic acid and 2-acrylamide-2-methylpropanesulfonic acid into ethyl alcohol, performing stirring, performing pressure reduction and vacuumizing to obtain a functional mixture, adding the repair liquid base material into the functional mixture to obtain the functional repair solution; S3, fully discharging the lead-acid storage battery; S4, adding the functional repair solution; S5, fully charging the lead-acid storage battery. The method provided by the invention is low in restoration cost, simple to operate,short in consumed time and good in restoration effect.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a method for quickly restoring the capacity of lead-acid batteries. Background technique [0002] Lead-acid batteries are widely used in transportation, communications, electric power, railways, mines, ports, national defense, Computers, scientific research and other fields are one of the more important products in social production and management activities and human life. However, with the increase in the use of lead-acid batteries, the number of scrapped batteries on the market has also increased, and how to deal with scrapped batteries is also an urgent problem to be solved. The most ideal solution is to repair the scrapped batteries to prolong the service life of the batteries. At present, the main reasons for scrapped batteries on the market are: dry electrolyte, slow charging speed, fast discharging speed, accumulation of lead sulfate crystals, etc. The repai...
