Lithium-Ion Battery Technology in Electric Vehicles
How Lithium-Ion Batteries Work
Lithium-ion batteries are electrochemical devices that store energy through the movement of lithium ions between two electrodes: the anode and the cathode. During charging, lithium ions flow from the cathode to the anode through an external electrical source. This process creates a chemical potential difference between the electrodes, storing energy. When the battery discharges, the ions flow back from the anode to the cathode, generating an electrical current that powers the vehicle.
The electrolyte, a liquid or gel-like substance, allows the lithium ions to move between the electrodes. The separator, a porous membrane, prevents the electrodes from coming into direct contact, preventing short circuits.
