Abstract

Lead acid battery is the most successful storage battery developed, its main application being in the automotive field. Despite its great versatility, storage characteristics and high degree of reversibility, it suffers from loss of water, stratification of electrolyte, grid corrosion, degradation of the active material etc. application of lead acid battery to electric vehicles and other repetitive deep cycle services produces and undesirable state in the cells of the battery known as electrolyte stratification. This is with the changes of the specific gravity of the sulphuric acid associated with the concentration changes during charge and discharge. It causes severe problems such as decrease in capacity and life in case of lead acid battery. Overcharging of the battery has been found to minimize the problem of stratification to some extent, but leads to deleterious effects. Hence, efforts have been made to design a simple and low power consuming electrolyte circulation system. Many researchers have tried and reported their results. In this paper, the authors present a detailed review regarding he consequences of electrolyte stratification on battery life and its capacity, about the methods employed to minimize its effect and also the results of the work.
