Abstract
The invention relates to the technical field of capacity recovery for valve control type lead-acid batteries and is characterized in that the formula comprises the following components by weight percent: 2-5% of sodium sulfate, 2-4% of potassium sulfate, 0.2-0.5% of aluminum sulfate, 1-3% of sodium bicarbonate, 1-2% of ammonium sulfate, 0.5-2% of phosphoric acid, 1-1.5% of sodium pyrophosphate, 0.05-0.15% of citric acid, 0.2-0.4% of ethylenediaminetetraacetic acid disodium and the balance of deionized water. Phosphate ions are fully utilized for protecting a cathode plate of the battery, thereby preventing active substances from being softened and shedding during the high-frequency pulse activation process and reducing the corrosion of a grid alloy; the action of a complexing agent is utilized for leading lead ions in a sulfide crystal to form a coordination compound and be further dissolved; and the action of replacing the lead ions in the sulfide crystal of active metal ions is simultaneously utilized for leading sulfate ions and the lead ions in the crystal to return into electrolyte. Not only can a cathode of the battery be effectively protected during the activation process based on the coaction of the components in the compound, but also the irreversible sulfation can be well eliminated, thereby greatly recovering the battery capacity with failure.

As follows to the such scheme content interpret:
In such scheme, be made into corresponding activation solution according to the content range of each component of mixture, then coordinate corresponding high-frequency impulse activating instrument, activation amount, can make battery repair reasonable effect.
In such scheme, the substances such as the phosphoric acid in component, sodium pyrophosphate make PbSO in corrosive film
4And PbO
2Content descends; PbO content increases, can effectively alleviate battery positive plate active material in high-frequency impulse activation softening and shedding, suppress sulfation, alleviate the grid alloy corrosion, improve the anodal life-span.In component, the complexing agent such as disodium ethylene diamine tetraacetate, citric acid can make lead ion formation complex in the sulfuration crystal, thereby slowly constantly makes accumulator plate break away from sulfation.In component, the active metal such as sodium sulphate, potassium sulfate ion can make favourable sulfate ion and the lead ion of its ionization paired storage battery of hydrolysis to the generation metathesis of lead ion in the sulfuration crystal, can well eliminate irreversible sulfation.
The present invention compared with prior art has following advantage:
1. activation solution of the present invention can be protected positive plate effectively, prevent its active material in repair process softening and shedding, can alleviate the grid alloy corrosion, extend the life of a cell.
2. activation solution of the present invention can be eliminated the irreversible sulfation of storage battery effectively, and the capacity of battery is recovered efficiently.
3. be substantially free of in the composition of activation solution of the present invention the disadvantageous ion of battery, can guarantee to repair the stable and lasting of rear battery capacity and life-span.
