It is important to note that the electrolyte in a lead-acid battery is sulfuric acid (H2SO4), which is a highly corrosive and dangerous substance. It is important to handle lead-acid batteries with care and to dispose of them properly. In addition, lead-acid batteries are not very efficient and have a limited lifespan.
In the case of a lead-acid battery, the chemical reaction involves the conversion of lead and lead dioxide electrodes into lead sulfate and water. The sulfuric acid electrolyte in the battery provides the medium for the transfer of electrons between the electrodes, resulting in the generation of electrical energy.
Current collectors in lead acid batteries are made of lead, leading to the low-energy density. In addition, lead is prone to corrosion when exposed to the sulfuric acid electrolyte. SLI applications make use of flat-plate grid designs as the current collectors, whereas more advanced batteries use tubular designs.
In a lead-acid battery, the ion such as proton in electrolyte (mainly the H2SO4 aqueous solution) also participates in both the discharge and recharge reactions. In other words, the sulfuric
