How 12v Flooded lead-acid battery works

Release time: 2022-11-10

The two sets of plates of the 12v Flooded lead-acid battery are inserted into the dilute sulfuric acid solution to generate a voltage by chemical changes. When direct current is applied (charging), the lead oxide on the positive plate becomes tan lead dioxide (PbO2), and the lead oxide on the negative plate becomes gray velvety lead (Pb, also called sponge-like). lead). When the lead battery is discharged, the active materials on the positive and negative plates absorb sulfuric acid and undergo a chemical change, and gradually become lead sulfate (PbSO4). When the active materials on the positive and negative plates become the same lead sulfate, The battery voltage drops to the point where it can no longer be discharged. The 12v Flooded lead-acid battery manufacturer tells you that you need to charge the battery at this time to restore it to the original lead dioxide and velvety lead, so that the battery can continue to discharge.

All batteries with an acidic aqueous solution as the electrolyte are collectively referred to as acid batteries, and the most typical one is lead-acid batteries. The main advantages of 12v Flooded lead-acid battery are high working voltage, wide operating temperature, good high and low rate discharge performance, rich source of raw materials and low price. The disadvantage is that the energy density is low, making it larger in size and weight.
12v Flooded lead-acid battery, the positive electrode is lead dioxide, the negative electrode is spongy lead, the electrolyte is sulfuric acid aqueous solution, and the separator (diaphragm) uses microporous rubber separator, microporous plastic separator or other separators according to different types of lead batteries Material, the battery shell is made of hard rubber, engineering plastics, FRP and other materials.
