How Lead-Acid Batteries Work
Working Principle of a Lead-Acid Battery. Lead-acid batteries are rechargeable batteries that are commonly used in vehicles, uninterruptible power supplies, and other applications that require a reliable source of power. The working principle of a lead-acid battery is based on the chemical reaction between lead and sulfuric acid.
11.5: Batteries
When an external voltage in excess of 2.04 V per cell is applied to a lead–acid battery, the electrode reactions reverse, and (PbSO_4) is converted back to metallic lead and (PbO_2). If the battery is recharged too vigorously, however, electrolysis of water can occur:
Lead–Acid Batteries
The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
The role of carbon in the negative plate of the lead–acid battery
In PSoC, lead negative electrode gradually becomes sulfated, and its capacity decreases rapidly. Various carbon additives inhibit the sulfation of Pb negative electrode [5], due to the improved ...

The chemical reactions are again involved during the discharge of a lead–acid battery.

It is important to understand what happens during the charging process when a battery is already fully charged.

Since there is no more …
