Abstract

The invention provides a repairing agent for lead-acid batteries, wherein the repairing agent for lead-acid batteries comprises sodium sulfate, ammonium sulfate, manganese dioxide, sodium hypophosphite, trifluoroacetic acid, ammonium phosphate and pyrogallol. In addition, the present invention also provides a repair method for a lead-acid battery, the method comprising: detecting battery capacity: putting the lead-acid battery to be repaired on a capacity detector for detection, stopping when the discharge reaches 10.5 volts, and selecting the discharge time Lead-acid battery for more than 30 minutes; add repair agent and deep discharge: the cover of the selected lead-acid battery, replenish electrolyte according to the situation, and add a certain proportion of repair agent according to the nominal capacity of the lead-acid battery to be repaired; then put Put the lead-acid battery on the discharge instrument, and deeply discharge the battery to zero volts; stand for deep dissolution: after the deep discharge is completed, let it stand for 10-60 minutes; charge: add a certain amount according to the nominal capacity of the lead-acid battery to be repaired Proportional restorer, then charge and let sit for 30‑90 minutes after full.

Description

technical field [0001] The invention relates to the field of repairing lead-acid batteries, in particular to a repairing agent for lead-acid batteries and a repairing method for lead-acid batteries. Background technique [0002] Lead-acid battery is a kind of chemical energy widely used in communication, electric power, railway, transportation and other fields. my country is a big country that produces and uses lead-acid battery in the world. There are hundreds of millions of batteries scrapped every year in our country, and it is increasing every year. Disposal of battery waste is a worldwide problem. Discarding it randomly will seriously pollute the environment and directly endanger human beings. [0003] Therefore, the repair of lead-acid batteries is a popular research topic worldwide. The life of lead-acid batteries is mainly determined by the corrosion deformation rate of the positive grid and the accumulation rate of irreversible sulfation. Generally speaking, the ...
