Schematic diagram of (a) discharge and (b) charge reactions that occur in Lead-acid batteries. During discharge mode, sulfuric acid reacts with Pb and PbO 2. It forms inherent lead sulfate, which is electrochemically inactive. Upon charge, the reaction occurs vice versa [3, , , , ], as described in Equations (2), (3)).
Lead-acid systems dominate the global market owing to simple technology, easy fabrication, availability, and mature recycling processes. However, the sulfation of negative lead electrodes in lead-acid batteries limits its performance to less than 1000 cycles in heavy-duty applications.
