In a lithium-ion battery, the cathode and anode are the two electrodes that enable the flow of electric charge. The cathode is the positive electrode, where reduction (gain of electrons) occurs, while the

The confusion mainly comes from the fact that their roles change depending on whether the battery is charging or discharging. In this guide, you''ll learn exactly what a battery anode and

Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if somewhat inaccurately, referred to as the cathode, and the

The cathode is made of a composite material (an intercalated lithium compound) and defines the name of the Li-ion battery cell. The anode is usually made out of porous lithiated graphite.

While the battery is discharging and providing an electric current, the anode releases lithium ions to the cathode, generating a flow of electrons from one side to the other. When plugging

The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode. In part because of lithium''s small atomic weight and radius (third only to
