The lead storage battery is the most important secondary cell. The cell reaction when the battery is in use are given below:
At anode: {tex}Pb(s) + SO_4^{2 - }(aq) \to PbS{O_4}(s) + 2{e^ - }{/tex}
At cathode: {tex}Pb{O_2}(s) + SO_4^{2 - }(aq) + 4{H^ + }(aq) + 2{e^ - } {/tex} {tex}\to 2PbS{O_4}(s) + 2{H_2}O(l){/tex}
The overall cell reaction is:
{tex}Pb(s) + Pb{O_2}(s) + 2{H_2}S{O_4}(aq) \to 2PbS{O_4}(s) + 2{H_2}O(l){/tex}
