Guide Lead-acid batteries and lead–carbon hybrid systems: A review
This review article provides an overview of lead-acid batteries and their lead-carbon systems. The formation of non-conductive PbSO 4 on the surface of the negative electrode during repetitive charge-discharge cycling produces an unstable system with a loss of capacity and poor cycle life. Therefore, advanced lead-acid systems developed in which

The fundamental elements of the lead–acid battery were set in place over 150 years ago 1859, Gaston Planté was the first to report that a useful discharge current could be drawn from a pair of lead plates that had been immersed in sulfuric acid and subjected to a charging current, see Figure 13.1.Later, Camille Fauré proposed the concept of the pasted plate.
Guide Examination of impact of lignosulfonates added to the negative
During discharge/charging, Pb 2+ ions are produced on the negative electrode, and further react with sulfuric acid to form a thin film of lead sulfate on the surface of the active mass and thus lead to unwanted passivation of the electrodes. From a practical point of view, this phenomenon can be prevented by the use of so-called expanders in the negative active mass
