What is a Lithium Battery?

Among the developed batteries, lithium-ion batteries (LIBs) have received the most attention, and have become increasingly important in recent years. Compared with other batteries, LIBs offer high energy density, high discharge power, high coulombic efficiencies, and long service life. These characteristics have facilitated a remarkable advance of LIBs in many frontiers, including electric vehicles, portable and flexible electronics, and stationary applications like BESS.

What are the major components of a Lithium Battery?

A battery consists of several key components: the anode, cathode, separator, electrolyte, and two current collectors (one positive and one negative).

1. Anode and Cathode:These are the electrodes where lithium ions are stored. The anode is typically the negative electrode, while the cathode is the positive electrode.
2. Electrolyte:This is a conductive medium that facilitates the movement of lithium ions between the anode and the cathode. It is usually a liquid or gel-like substance.
3. Separator:Positioned between the anode and cathode, the separator prevents direct electrical contact between them while allowing the passage of lithium ions through it.
4. Current Collectors:These are conductive materials attached to the anode and cathode that  collect and transfer electrical current to and from the external circuit.
