Lead ingots are used to produce valve-regulated sealed lead-acid batteries. As the price of lead has increased worldwide, various domestic public and private companies have been forced to increase their budgets to replace numerous batteries each year. In the disrupted global economic situation, this generates a budgetary challenge. In this study, regeneration technology was applied to extend battery life, reduce costs and pollution, and conserve energy.
Instead of employing general automotive lead-acid batteries, the researcher regenerated valve-regulated lead-acid batteries, which account for the highest percentage of the total product value in the lead-acid battery market, facilitating economically beneficiary regeneration, and exhibiting market potential. The same regeneration theory is applied to various regeneration technologies. To regenerate lead-acid batteries, the lead sulfate crystals inside are dissolved and reduced to a negative lead electrode plate of lead and a positive lead dioxide battery plate of lead dioxide. After evaluating several regeneration technologies, the researcher employed the shark-pulse technique technology for the regeneration experiment and assessed its theoretical feasibility and logic. Regeneration experiments were conducted using multiple batteries, examining whether the regenerated batteries met actual usage requirements or demonstrated only temporary effectiveness.
The experimental results showed that the discharge performance of regenerated batteries was many folds higher compared with pre-regeneration batteries. Therefore, battery regeneration technology substantially contributes to cost reduction, energy conservation, and environmental protection.
