How rechargeable batteries, charging, and discharging cycles work
The Discharge of the lead-acid battery causes the formation of lead sulfate (PbSO 4) crystals at both the positive electrode (cathode) and the negative electrode (anode), and release electrons due to the change in valence charge of the lead. This formation of lead sulfate uses sulfate from sulfuric acid which is an electrolyte in the battery.
