When you use a device that’s powered by a lithium-ion battery, it’s in the discharge cycle:Lithium ions in the anode move through the electrolyte to the cathode. As the ions travel, they release stored energy.This movement of ions generates electrons, which flow through the external circuit to power the device (like your smartphone, laptop, or electric vehicle).As the ions move toward the cathode, the anode loses lithium, and the battery discharges, providing power to your device.
