Project Report on Lead Battery Plates & Battery Assembly [Eiri-0929]

Lead-Acid Battery comprises number of cells in a container. These cells contain positive (PbO2) and negative (Pb) electrodes or plates separators to keep the plate apart and sulphuric acid electrolyte. The electtrochemical system is highly reversible and sulphuric acid electrolyte. The electro chhemical system is highly reversible and can be discharged and charge repeatedly before failure of some sort causes the chargocyde to be impractical. There are numerous  battery designs. The most widely used secondary battery is the lead acid type. This battery is available in many sizes and capacities and the weight can vary from 100g to several tons. There on three principal catagories. The material used for containers used depends on the application eg. polypropylene and vulcanized rubber for automotive balleries, polystyrene for stationery batteries, polycarbonate for a large single cell and ABS plastic and drawn steel cans for sealed lead cells. All plastic and rubber containers are molded. The container serves to hold the battery contents without determation, to allow the cell plates to rest on the bottom ridges and to separate the cells, in some cases by compartment positions. Physical qualities are required of the container are; to resist attack by sulphuric acid solution and the battery components, to be nonporous, be nonreactive, and to withstand extrems of heat and as well as shock and vibration.
