What lithium batteries are used for?

Lithium batteries, primarily lithium-ion batteries (LIBs), are widely used in our daily life, such as in mobile phones, tablets, and cameras. In the LIB system, carbon materials usually replace the metal lithium to store and release lithium ions in the electrochemical process.

What is a lithium battery?

The primary function of a lithium battery is to provide power to operate devices such as mobile phones, laptops, cars, and so on. The typical lithium-ion battery includes anode and cathode electrodes immersed in an electrolyte solution. When one electrode is connected to the positive terminal of a battery charger or power supply and the other electrode is connected to the negative terminal of the battery charger or power supply, electrons are transferred from one electrode to another through an external circuit. This causes an oxidation-reduction reaction at both electrodes that results in a flow of current through an external circuit.
