A lead acid cell is an electrochemical cell, comprising of a lead grid as an anode (negative terminal) and a second lead grid coated with lead oxide, as a cathode (positive terminal), immersed in sulfuric acid. The concentration of sulfuric acid in a fully charged auto battery measures a specific gravity of 1.265 – 1.285.
This experiment can be used as a class practical or demonstration. Students learn how to construct a simple lead–acid cell consisting of strips of lead and an electrolyte of dilute sulfuric acid. The cell should then be charged for different lengths of time, before being discharged through a light bulb.
Verify the effect of Temperature on the Cell Potential of the lead acid cell. Verify the effect of Activity (or concentration) of reacting species on the Cell Potential of the lead acid cell. Examine the effect of Electrode Composition on the Cell Potential of the lead acid cell.
Using equation 8, the Nernst equation for the lead acid cell is, Where a s’ are the activities of the reactants and the products of the cell. (11) Note: n= 2 n = # of moles of electrons involved in the oxidation-reduction reactions in equations, 1 and 2, above. + and SO4 -2 ions in H2SO4, on the cell potential.
For most lead-acid battery subsystems it is necessary that they be charged by voltage regulator circuits properly compensated for changes in operating temperature. The number of cells in series is obtained by dividing the maximum system charge voltage by the maximum charge voltage in volts per cell specified by the cell manufacturer.
Operating temperature of the battery has a profound effect on operating characteristics and the life of a lead-acid battery. Discharge capacity is increased at higher temperatures and decreased at lower temperatures. At higher temperatures, the fraction of theoretical capacity delivered during discharge increases.
