Part 8. Lead-Acid battery electrolyte. The electrolyte of lead-acid batteries is a dilute sulfuric acid solution, prepared by adding concentrated sulfuric acid to water. When charging, the acid becomes more dense due to the formation of lead oxide (PbO2) on the positive plate. Then it becomes almost water when fully discharged.

View moreThe lead – acid battery is made up of a series of cells. One cell consists of a lead peroxide positive plate and a lead negative plate both immersed in a dilute sulphuric acid solution. The sulphuric acid is known as the ‘electrolyte’. In other words, lead acid batteries often use sulphuric acid as the major component of the electrolyte.
In other words, lead acid batteries often use sulphuric acid as the major component of the electrolyte. A battery electrolyte is an acid or a base that dissociates into positive and negative charged ions that react with the anode and cathode as a battery undergoes an oxidation-reduction reaction.
Chemically, a lead-acid dry cell battery has a zinc anode and a carbon rod/manganese dioxide cathode. The electrolyte is generally an acidic paste. An electrolyte consists of a mixture of ammonium chloride and zinc chloride. Physically, a lead acid battery is constructed the reverse of an alkaline battery.
The recovery of lead acid batteries from sulfation has been demonstrated by using several additives proposed by the authors et al. From electrochemical investigation, it was found that one of the main effects of additives is increasing the hydrogen overvoltage on the negative electrodes of the batteries.
Sulfation prevention remains the best course of action, by periodically fully charging the lead–acid batteries. A typical lead–acid battery contains a mixture with varying concentrations of water and acid.
Offers high safety. Chemicals present in an alkaline battery are not harmful, they only cause mild effects like irritation. This is opposite to a lead-acid battery which has very poisonous lead metal and a corrosive acid. This means if an alkaline battery explodes it will cause minimal damage, while a lead acid will cause massive damage.
