Lead–acid battery fundamentals

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 …

Design aspects of the valve regulated lead/acid battery positive electrode

Experimental results obtained from the study of 12. V, 40 Ah, valve regulated lead/acid (VRLA) batteries indicated that reduction in capacity during cycling can be attributed to changes in the positive electrode.. Corrosion layer (CL) growth has been identified as a key factor that can lead to a reduction in performance and eventual battery failure.
