The lead storage battery is as shown in diagram. Lead storage battery consists of lead anode and a grid of lead packed with lead oxide( ${PbO}_{2}$ ) as cathode, a $38 %$ solution of $H_{2} {SO}_{4}$ is used as an electrolyte. During charging of battery ${PbSO}_{4}$ deposited on cathode is converted in ${PbO}_{2}$ and ${PbSO}_{4}$ deposited on anode is converted into $Pb$ . The electrolyte used in battery is $H_{2} {SO}_{4}$ which is about $38 %$ by mass.
