A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions take place at the electrodes:
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
Lead acid batteries have reasonably good charge efficiency. Modern designs achieve around 85-95%. The amount of time and effort required to recharge the battery indicates this efficiency. This emphasizes the significance of repetitive charging as a component of applications.
A lead acid cell is charged at the rate of 18 A for 10 hours at an average voltage of 2.26 Volts. It is discharge in the same time at the rate of 17.2 A; the average voltage during discharge being 1.98 V. Calculate the Ampere-hour eff of the cell?
