High-potential zinc–lead dioxide rechargeable cells ...

A zinc–lead dioxide rechargeable cell with an electrolyte composition of 1.5 mol dm −3 Zn(II), 0.5 mol dm −3 Na(I) and 0.3 mol dm −3 sulfuric acid is proposed and tested. The experimental results show that the open circuit potential of the zinc–lead dioxide cell is as high as 2.4 V (20% higher than conventional lead-acid cells and 56% higher than recent copper–lead dioxide cells ...

Uses of Lead | Lead Deposits and Resources

Lead commonly occurs in mineral deposits along with other base metals, such as copper and zinc. Lead deposits are broadly classified on the basis of how they are formed. Lead is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).

Electrode Potential and Galvanic Corrosion

The potential difference between an anode and a cathode can be measured by a voltage measuring device but since the absolute potential of an anode or cathode cannot be measured directly - all potential measurements are made against a standard electrode. The standard electrode potential is set to zero and the measured potential difference can be considered as absolute.
