Nickel-Metal Hydride (Ni-MH) rechargeable batteries are a type of secondary battery that uses a combination of a nickel oxide positive electrode (cathode), a hydrogen-absorbing negative electrode (anode), and an alkaline electrolyte. These batteries are designed to be recharged and reused multiple times, making them a more environmentally friendly alternative to disposable alkaline batteries.
Explanation: Ni-MH batteries operate based on the principle of electrochemical reactions. During discharge (when the battery is in use), the chemical reactions between the nickel oxide and hydrogen-absorbing alloy create an electric current. When charging, the process is reversed: an external voltage is applied to force the hydrogen back into the negative electrode and restore the battery's capacity.
