A coin battery, also known as a button cell, generates electrical energy through electrochemical reactions between its internal components. It typically consists of two electrodes—a positive cathode and a negative anode—separated by an electrolyte. When the battery is connected to a circuit, chemical reactions occur at the electrodes, releasing electrons that flow through the circuit, providing power to devices. These batteries are commonly used in small electronics like watches, calculators, and hearing aids due to their compact size and reliability.
