Project Report on Lead Acid Battery

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 electrochemical system is highly reversible  and sulphuric acid electrolyte. The electrochhemical 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 100 g to several tons, There on three principal  categories. The material used for containers used depends on the  application e.g.   polypropylene  and   vulcanized  rubber   for   automotive  batteries, 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 determination,  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 extremes of heat and as well  as shock and vibration.
