During charging, the lead-acid battery undergoes a reverse chemical reaction that converts the lead sulfate on the electrodes back into lead and lead dioxide, and the sulfuric acid is replenished. This process is known as "recharging" and it restores the battery''s capacity to store electrical energy.
In this study, we present a low-cost and simple method to treat spent lead–acid battery wastewater using quicklime and slaked lime. The sulfate and lead were successfully removed using the precipitation method. The structure of quicklime, slaked lime, and resultant residues were measured by X-ray diffraction. The obtained results show …
Desulfation in Lead-acid Batteries; a Novel (resistive) Approach: A major life-limiting problem with lead-acid batteries is that when discharged (partially or otherwise) the resulting lead-sulfate slowly transforms into an insoluble form that eventually disables the battery. (A charged battery is shown, where no l…
The global lead-acid battery industry is worth about $65 billion annually, but when used batteries are recycled, the process has been identified as the most polluting in the world.
