The same principle as in a Daniell cell, where the reactants are higher in energy than the products, 18 applies to a lithium-ion battery; the low molar Gibbs free energy of lithium in the positive electrode means that lithium is more strongly bonded there and thus lower in energy than in the anode.
The cathode of a lithium-ion battery is mainly composed of a lithium compound, while the prime element of the anode is graphite. When the battery is plugged in with an electric supply, the lithium ions tend to move from the cathode to the anode, i.e., from the positive electrode to the negative electrode.
A lithium-ion battery, also known as the Li-ion battery, is a type of secondary (rechargeable) battery composed of cells in which lithium ions move from the anode through an electrolyte to the cathode during discharge and back when charging.
