BRAINCAKERechargeable Batteries
The reactions in rechargeable cells can be reversed using electrical energy so the cell can be re-used. Examples are Ni-Cd (nickel-cadmium) batteries, lithium-ion batteries and lithium polymer batteries used in laptops. Lead-acid batteries are used in cars. Each cell has two lead plates. The cathode is coated with lead (IV) oxide. The electrolyte is concentrated sulfuric acid. At the anode:
Pb(s) + SO42-(aq) → PbSO4(s) + 2e-
