3.2.2 Lead-Acid Battery Materials. The lead-acid battery is a kind of widely used commercial rechargeable battery which had been developed for a century. As a typical lead-acid battery electrode material, PbO 2 can produce pseudocapacitance in the H 2 SO 4 electrolyte by the redox reaction of the PbSO 4 /PbO 2 electrode.
The most familiar example of a flooded lead-acid cell is the 12-V automobile battery. Sealed Lead-Acid Batteries. These types of batteries confine the electrolyte, but have a vent or valve to allow gases to escape if internal pressure exceeds a certain threshold. During charging, a lead-acid battery generates oxygen gas at the positive electrode.
At discharge, the lead is converted into lead sulphate (a white powder in the open air) while the sulphuric acid content decreases in the acid solution (i.e., the density drops to 1.0 = only
Wired in parallel, one damaged battery can destroy all others. When a lead acid battery reaches the end of its life, it can sometimes happen that a single cell inside the battery is short-circuited. 12 V lead batteries are made of 6 cells that are wired in series.
Why Lead-Acid Batteries Are Still a Popular Choice for UPS Systems. • Condensed or frozen electrolyte that has lost its density; • Damage to the battery case due to impact or mechanical stress; If the density of the electrolyte drops to 50% of the battery capacity, the liquid will freeze at -24°C or -11.2°F.

When a current is being drawn from the battery, the sudden drop is due to the internal resistance of the cell, the formation of more sulphate, and the abstracting of the acid from the electrolyte which fills the pores of the plate. The density of this acid is high just before the discharge is begun.
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.
Normally, as the lead–acid batteries discharge, lead sulfate crystals are formed on the plates. Then during charging, a reversed electrochemical reaction takes place to decompose lead sulfate back to lead on the negative electrode and lead oxide on the positive electrode.
Sulfation , which means the formation of PbSO 4, is another serious problem with lead–acid batteries. Normally, as the lead–acid batteries discharge, lead sulfate crystals are formed on the plates.
Lead-acid storage battery will lose part of its capacity due to self-discharge. Therefore, before lead-acid battery is installed and put into use, the remaining capacity of the battery should be judged according to the battery's open circuit voltage, and then different methods should be used for supplementary charge for the battery.
