How Does a Battery Cell Generate Electricity Through Chemical Reactions?

A battery cell generates electricity through chemical reactions. It contains two electrodes: a positive electrode (cathode) and a negative electrode (anode). The electrodes are immersed in an electrolyte solution, which facilitates the movement of ions.

When a battery is connected to an external circuit, a chemical reaction occurs at the anode. The anode undergoes oxidation, releasing electrons. These electrons travel through the external circuit, creating an electric current.

Simultaneously, at the cathode, a reduction reaction occurs. The cathode gains electrons from the external circuit. This movement of electrons from the anode to the cathode produces a flow of electric current.

The electrolyte allows ions to move between the electrodes. This flow complements the movement of electrons and maintains balance in the battery. The continuous chemical reactions at both electrodes sustain the electric current until the reactants are depleted.

Thus, electricity generation in a battery cell happens through the oxidation and reduction of materials at the electrodes, facilitated by the electrolyte.
