How Do Lithium Ion Batteries Work? A Step-by-Step Explanation

When a lithium-ion battery is charging, lithium ions move from the cathode (positive electrode) to the anode (negative electrode) through the electrolyte. The anode, usually made of graphite, acts as a host for these lithium ions, which get stored in its layered structure. At the same time, electrons are forced to move through an external circuit from the positive

What happens when a lithium ion battery is charged?

When a Li-ion battery is charged, the active material on the positive electrode releases part of its Li ions, which flows through the electrolyte to the negative electrode and remains there, storing energy in the battery. When the battery is discharging, the opposite processes occur.

What are the main features of a lithium-ion battery?

Let us first briefly describe the main features of a lithium-ion battery and then point out the important role of voids in it. There are four components in a lithium-ion cell: anode, cathode, separator, and the nonaqueous electrolyte.
