Understanding Sulfation and Recovery in Lead Acid Batteries

Recharging the battery reverses the chemical process; the majority of accumulated sulfate is converted back to sulfuric acid. Desulfation is necessary to remove the residual lead sulfate, restoring capacity and run time. What is sulfation? Sulfation occurs each time a battery is discharged and is a normal part of battery operation. The process

6 FAQs about [Sulfuric acid battery processing]

Does sulfuric acid roasting work for selective lithium extraction from discarded lithium-ion batteries?

Does sulfuric acid baking & water leaching reduce the consumption of spent cathode active material?

Therefore, this work aims the novelty of sulfuric acid baking and water leaching of the spent cathode active material with the purpose of operating the same at comparatively lower temperature than that of the alkali roasting processes, besides ensuring lower acid consumption compared to the direct sulfuric acid leaching.

What happens if a battery sulfates?

ulfates will accumulate and build up on the battery plates. The sulfation process is accelerated if the battery is left in a discharged state for a prolonged time; or is not properly and regularly equalized. This leads to the development of large crystals that reduce the battery’s active ma
