Lithium-ion battery (LIB) is one of rechargeable battery types in which lithium ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge, and back when charging. It is the most popular choice for consumer electronics applications mainly due to high-energy density, longer cycle and shelf life, and no memory effect.

The overall performance of the LIB is mostly determined by its principal components, which include the anode, cathode, electrolyte, separator, and current collector. The materials of the battery's various components are investigated. The general battery structure, concept, and materials are presented here, along with recent technological advances.
Another significant issue to the lithium ion battery is dendrite formation. This dendrite is often formed on the anode side of a lithium ion battery. Its existence is similar to a microstructure. During the charging period, dendrite formation begins on the anode and progresses to the cathode of the battery.
