Abstract: The sodium sulphate in the electrolyte and its influence on the electrochemical characteristics such as capacity, reserve capacity, cold cranking ampere, high rate discharge and charge acceptance of the lead acid battery have been investigated.
Sodium sulfate as an additive in the electrolyte solution of a 2V/20AH lead acid battery to determine the effect on the cycle life and performance of the battery has been investigated. The electrolyte solution was a combination of sulfuric acid and sodium sulfate with charge and discharge cycle processes carried out for 30 minutes each.
The sodium sulphate in the aqueous sulphuric acid electrolyte acts as buffer solution and also expected to improve the reversibility of redox reaction in the lead acid battery. Further, the density of the electrolyte changes with Na2SO4concentration in the electrolyte and the same is depicted in Fig.2.
On recharge, the lead sulfate on both electrodes converts back to lead dioxide (positive) and sponge lead (negative), and the sulfate ions (SO 42 ) are driven back into the electrolyte solution to form sulfuric acid. The reactions involved in the cell follow. At the positive electrode: At the negative electrode: Over cell:
Additive effects of aluminium sulfate in the sulfuric electrolyte solution of lead acid battery had no improvement on the charge cycle and stability of the cathode with reference to the battery made of dilute sulfuric acid electrolyte.
