Abstract: In this study, we examined the recovery of sulfated flooded battery with the help of organic polymer compounds as activator. Battery samples, after having ensured that they were heavily sulfated were considered for the purpose of recovery. A desulphation revival solution was prepared with the selected polymer compounds and tested. The sulphated batteries were divided into two groups (Group A-Control, Group B-Trial) for optimization of desulfation solution parameters (concentration and volume of solution per cell) respectively. The effect of these two parameters on the recovery process was optimized by considering one parameter at a time. For this purpose, different concentrations of desulfation revival solution having different volumes were added to discharged sulfated batteries and the batteries were subjected to charging with C20 current up to 16V per battery for 12 hr. The control samples were subjected to similar charge regime but without desulfation revival solution added. Discharge capacity and charge/discharge cycle (endurance performance) behavior of the recovered batteries were investigated and compared with control sample. The electrode samples were characterized by XRD, SEM to understand the phase composition and crystal morphology of test samples before and after recovery process to assess the degree of capacity and active material restoration.
