Lead-acid batteries are one type of secondary cell. Primary and secondary cells differ in that, unlike secondary cells, primary cells cannot be recharged and reused as a source of electrical energy. In the case of secondary cells, it is possible to repeat the process of recharging in the order of hundreds to thousands of cycles. Recharging is limited only by the degradation mechanisms occuring in each type of accumulator. Currently, technologies based on the production of renewable electricity are increasingly being used. Due to their properties, recycling possibilities, the high number of cycles, and low purchase price, lead-acid batteries are an interesting alternative for these energy storage from renewable sources. Lead-acid batteries, like other types of batteries, are subject to a large number of degradation mechanisms that significantly reduce the capacity and lifetime of the batteries. Degradation mechanisms in accumulators are closely related to the materials used. In the case of improvement of one of the undesirable properties, there is usually a deterioration of other properties. One of the most significant degradation mechanisms are PCL phenomena (Premature Capacity Loss). Currently, the most problematic phenomenon is PCL 3. In the PCL 3 phenomenon, the negative electrode is sulfated. A fine layer of lead sulfate forms on the surface of the negative electrode, prevents the movement of ions and causes the battery capacity to decrease. PCL 3 is also associated with the selective discharge of the negative electrode and reduction of lead acid battery cycles.
