Agnieszka et al. studied the effect of adding an ionic liquid to the positive plate of a lead-acid car battery. The key findings of their study provide a strong relationship between the pore size and battery capacity. The specific surface area of the modified and unmodified electrodes were similar at 8.31 and 8.28 m 2 /g, respectively [75]. In ...
In the charged state, the positive active-material of the lead–acid battery is highly porous lead dioxide (PbO 2). During discharge, this material is partly reduced to lead sulfate. In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead.
While you certainly don''t want to keep your battery in an undercharged state, overcharging is just as bad. Continuous charging can: cause corrosion of the positive battery plates; cause increased water consumption; even allow for excessive temperatures causing damage inside the battery. This continuous heating from overcharging can destroy a ...

Explanation: When the battery is fully charged there is lead peroxide on the positive plate and lead spongy on the negative plate as an active material. During the process of discharge, the chemical reactions forms lead sulphate on both the plates thereby liberating water.
In a lead-acid cell the active materials are lead dioxide (PbO2) in the positive plate, sponge lead (Pb) in the negative plate, and a solution of sulfuric acid (H2SO4) in water as the electrolyte. The chemical reaction during discharge and recharge is normally ... Lead-acid battery types which are now commercially available are classified by ...
