Nickel cadmium battery chemical equation. The chemical reaction in a nickel-cadmium battery can be expressed as: The first equation describes the interaction between the cathode layer, nickel, and the separator, producing nickel oxide and OH ions. The isolation layer is essential to provide the OH ions required for this reaction.
Ni-Cadmium Batteries
The nickel–cadmium secondary battery contains NiOOH/nickel hydroxide as a positive active material, cadmium/cadmium hydroxide as a negative active material, and an aqueous solution containing potassium hydroxide as the main component as an electrolyte. Generally the charge-and-discharge reaction is shown in the following …
