When the battery is charging, the lithium ions flow from the cathode to the anode, and the electrons move from the anode to the cathode. As long as lithium ions are making the trek from one electrode to another, there is a constant flow of electrons. This provides the energy to keep your device running.
What happens in a lithium-ion battery when discharging (© 2019 Let's Talk Science based on an image by ser_igor via iStockphoto). When the battery is in use, the lithium ions flow from the anode to the cathode, and the electrons move from the cathode to the anode. When you charge a lithium-ion battery, the exact opposite process happens.

When the lithium-ion battery in your mobile phone is powering it, positively charged lithium ions (Li+) move from the negative anode to the positive cathode.
This results in the reduction of Co(IV) to Co(III) when the electrons from the anode reaction are received at the cathode. Because lithium is involved in the reactions at both electrodes, the battery can be recharged by running the reactions in reverse. These reactions can be run in reverse to recharge the cell.
