Discharge and Charge Process of a Conventional Lithium-Ion Battery Cell

Discharging During the first stage of discharge lithium atoms oxidize by forming Li ions and electrons, whereas Li ions move to the positive electrode diffusing through the electrolyte and the separator. The electrons flow from the negative electrode to the positive on the external circuitry, where the resulting current flow can be used for an application. At the positive electrode the electrons recombine with the Li ions and are stored in the molecular structure of the active material. Charging:
