Describe lead storage battery

Explanation

It is a secondary cell, mainly used in auto mobiles.
Anode -Lead
Cathode, Gride of lead packed with `PbO_(2)`
Electrolyte 38% sulphuric acid
Cell reactions:
Anode: `Pb(s)+SO_(4)^(2-)(aq) to PbSO_(4)(s)+2e^(-)`
Cathode: `PbO_(2)(s)+SO_(4)^(2-)(aq)+4H^(+)+2e^(-) to PbSO_(4)(s)+2H_(2)O`
Overall reaction `Pb(s)+PbO_(2)(s)+2H_(2)SO_(4)(aq) to 2PbSO_(4)(s)+2H_(2)O(l)`
