How Do Lithium-Ion EV Batteries Work?
Lithium-ion EV batteries operate through reversible chemical reactions between the cathode and anode, facilitating the flow of lithium ions to generate and store electrical energy, thereby powering electric vehicles efficiently and sustainably.
When an EV is turned on, its lithium-ion battery enters the discharging phase, and a chemical reaction occurs within the battery, causing lithium ions to migrate from the cathode to the anode. This flow of lithium ions generates electrical energy that powers the vehicle’s electric motor, propelling it forward.
Conversely, when the EV is turned off or plugged into an electrical outlet for charging, the battery enters the charging phase. In this phase, the chemical reaction reverses, with lithium ions moving from the anode back to the cathode, where they are stored for future use.
Additionally, during regenerative braking, excess kinetic energy produced by the EV is converted into electrical energy. This energy is utilized to recharge the battery, with the flow of lithium ions from the anode to the cathode contributing to energy storage.
