If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes). These batteries only work in one direction, transforming chemical energy to electrical energy. But in other types of batteries, the reaction can be reversed.
The current in the battery arises from the transfer of electrons from one electrode to the other. During discharging, the oxidation reaction at the anode generates electrons and reduction reaction at the cathode uses these electrons, and therefore during discharging, electrons flow from the anode to the cathode.
The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.
Many important chemical reactions involve the exchange of one or more electrons, and we can use this movement of electrons as electricity; batteries are one way of producing this type of energy. The reactions that drive electricity are called oxidation-reduction (or "redox") reactions.
A battery is a device that converts chemical energy directly to electrical energy. Describe the functions and identify the major components of a battery A battery stores electrical potential from the chemical reaction.
Such reactions reduce stability and create safety concerns as they can cause catastrophic internal battery failure leading to uncontrollable reactions and thermal runaway that can cause batteries to rupture, ignite, or explode.
