The negative electrode of lead-acid battery has a special failure mechanism called sulfation [ 12]. During discharging, the lead crystals in the negative electrode are transformed into lead sulfate crystals.
During the charging process of batteries, condensed crystals of lead sulfate, as nonconductive materials, cannot be converted back into the active materials in the negative plate. Therefore, Lead-Acid batteries mostly suffer from this type of failure during the deep discharge, which considerably decreases life time of the battery.
The recovery of lead acid batteries from sulfation has been demonstrated by using several additives proposed by the authors et al. From electrochemical investigation, it was found that one of the main effects of additives is increasing the hydrogen overvoltage on the negative electrodes of the batteries.

Conclusion One of the main problems of Lead-Acid batteries that happens during the charge/discharge cycle is aggregation of the condensed crystals of lead sulfate in their negative plate. This may result in nonconductive negative plates with a reduced capacity.
Rechargeable Lead-Acid battery was invented more than 150 years ago, and is still one of the most important energy sources in the daily life of millions of peoples. Lead-Acid batteries are basically divided into two main categories : (1) Starting-Lighting-Ignition (SLI) batteries, and (2) deep cycle batteries.
