- During discharge (battery providing power), oxidation occurs at the anode, releasing electrons and lithium ions. Electrons flow through the external circuit, and lithium ions move through the electrolyte to the cathode. - At the cathode, reduction occurs as lithium ions accept electrons and are incorporated into the cathode material. - The flow of electrons in the external circuit constitutes the electric current.
