3.2.2 Lead-Acid Battery Materials. The lead-acid battery is a kind of widely used commercial rechargeable battery which had been developed for a century. As a typical lead-acid battery electrode material, PbO 2 can produce pseudocapacitance in the H 2 SO 4 electrolyte by the redox reaction of the PbSO 4 /PbO 2 electrode.
This primarily takes place because of the low atomic mass of lithium as compared to lead (6.9 u for lithium and 207 u for lead) and also due to higher cell voltage attained in the case of lithium as compared to the lead–acid battery (3.6 V in case of lithium and 2.1 in case of lead–acid battery).
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 electrode …
