Many services to improve the performance of lead acid batteries can be achieved with topping charge (See BU-403: Charging Lead Acid) Adding chemicals to the electrolyte of flooded lead acid batteries can dissolve the buildup of lead sulfate on the plates and improve the overall battery performance.
Adding chemicals to the electrolyte of flooded lead acid batteries can dissolve the buildup of lead sulfate on the plates and improve the overall battery performance. This treatment has been in use since the 1950s (and perhaps longer) and provides a temporary performance boost for aging batteries.
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 material, decreasing the battery’s capacity and performance.
Although end-of-life (EOL) batteries are estimated to become a significant source of secondary cobalt in the future, recycled cobalt alone will not be nearly enough to satisfy the increasing demand during the next decade (Alves Dias et al. 2018 ).
Over time, small sulfate crystal formation is normal and not harmful to the battery. During each charge/discharge cycle, the sulfates 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.
Cobalt sulfate was recovered from crushed and screened prismatic type spent lithium ion batteries (LIBs) containing 5–20% Co, 5–7% Li, 5–10% Ni, 15% organic chemicals, and 7% plastics together with Cu, Al, Fe, and Mn.

Lithium-ion vs. Lead Acid: Performance, Costs, and Durability
Lead-acid batteries rely primarily on lead and sulfuric acid to function and are one of the oldest batteries in existence. At its heart, the battery contains two types of plates: a lead dioxide (PbO2) plate, which serves as the positive plate, and a pure lead (Pb) plate, which acts as the negative plate. With the plates being submerged in an electrolyte solution made from a diluted form of ...

Understanding Sulfation and Recovery in Lead Acid Batteries
Supplying energy to an external load discharges the battery. During discharge, both plates convert to lead sulfate (PbSO 4) and the electrolytes becomes less acidic. This reduces the specific gravity of the solution, which is the chemical "state of charge" of the battery.
