The processes that take place during the discharging of a lead–acid cell are shown in schematic/equation form in Fig. 3.1A can be seen that the HSO 4 − ions migrate to the negative electrode and react with the lead to produce PbSO 4 and H + ions. This reaction releases two electrons and thereby gives rise to an excess of negative charge on …
The importance of the porosity of the active material in lead-acid battery electrodes has been widely debated and various authors have discussed the optimal porosity and its role in the battery electrochemistry during charge and discharge [1], [6], [7], [8].
