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.
The charging and discharging of lithium ion battery is actually the reciprocating movement of lithium ions and free electrons. Different metals have different electrochemical potentials. Electrochemical potential is the tendency of metals to lose electrons. The electrochemical potentials of some common metals are shown in the figure below.

A battery typically consists of two electrodes, namely, anode and cathode.
All lithium-ion batteries work in broadly the same way. When the battery is charging up, the lithium-cobalt oxide, positive electrode gives up some of its lithium ions, which move through the electrolyte to the negative, graphite electrode and remain there. The battery takes in and stores energy during this process.
