Positive plates are usually produced by Plante Process and the plates are known as Plante Plates. The negative lead acid battery plates can also be manufactured by this process but for negative plate this process is impracticable.
Lead Acid Battery Definition: A lead acid battery is defined as a rechargeable battery that uses lead and sulfuric acid to store and release electrical energy. Container Construction: The container is made from acid-resistant materials and includes features to support and separate the plates.
The negative lead acid battery plates can also be manufactured by this process but for negative plate this process is impracticable. In Faure process, the active material is mechanically applied instead of being electrolytically developed out of lead plate itself as in Plante process.
Two lead plates after being subjected to hundreds of reversals will acquire a skin of lead peroxide thick enough to process sufficiently high capacity. This process of making positive plates is known as formation. The negative lead acid battery plates are made by same process.
There are mainly two parts in a lead acid battery. The container and plates. As this battery container mainly contains sulfuric acid hence the materials used for making a lead acid battery container must be resistant to sulfuric acid. The material container should also be free from those impurities which are deterious to the sulfuric acid.
In order to obtain large capacity in smaller construction of lead acid battery, a large surface must be exposed to the electrolyte, and since the size of a single plate is limited, so to increase capacity of lead acid battery, number of negative and positive plates are connected in parallel.
