The LEAD material takes center stage in storage batteries, particularly the common lead-acid battery. In such configurations, lead is used on both sides. Sponge lead is used as the anode, while lead dioxide is the active component of the cathode. It loves being recharged and reused repeatedly because of its high reversibility. It is also a good conductor of electricity; hence, amps move freely. Moreover, it won’t cost an arm and a leg because lead is relatively inexpensive.
