A battery is a device that converts chemical energy into electrical energy. It achieves this through a process called electrochemical oxidation-reduction reactions, also known as redox reactions. A battery consists of three fundamental components: an anode (negative electrode), a cathode (positive electrode), and an electrolyte. The anode is where oxidation occurs, meaning electrons are released. These electrons then flow through an external circuit, powering any connected device, before reaching the cathode, where reduction occurs, meaning electrons are gained. The electrolyte is a conducting medium that allows ions (charged atoms) to move between the anode and cathode, completing the circuit and sustaining the chemical reaction. Different battery types use various materials for the anode, cathode, and electrolyte, which affects the battery's voltage, energy density, and lifespan. For instance, a common alkaline battery uses zinc for the anode, manganese dioxide for the cathode, and a potassium hydroxide solution as the electrolyte. As the battery discharges, the chemical reaction proceeds, gradually consuming the electrode materials and reducing the battery's capacity to provide power until it is eventually depleted. Rechargeable batteries can reverse this chemical process through an external electrical charge, restoring their capacity to provide power.
