Previous Technique Traditional lead-acid batteries do not use any additives. The battery's charging and discharging processes are carried out. However, this is the case today. This condition, known as sulfation in batteries, seriously affects battery performance. This leads to a problem that has a negative impact. Sulfation, especially at the negative electrodes. It is formed by the formation and accumulation of lead sulfate (PbSO₄) crystals. The issue is accumulation, where active material is becoming increasingly passive and the battery... This leads to a decrease in its capacity. As a result, the battery's ability to accept charge decreases. It is declining, cycle life is shortening, and performance losses are occurring. Lead sulfate crystals accumulate on the negative electrodes during the charging process. By not dissolving, it reduces the battery's capacity and efficiency. This situation This leads to a shorter battery cycle life and a decrease in performance.
