A lithium ion battery (sometimes written as Li-ion battery or LIB) is a type of rechargeable battery commonly used for consumer electronics, as well as other applications. Lithium ions in these batteries move from the negative electrode to the positive during discharge, and from the positive electrode to the negative while recharging. Li-ion batteries come in a broad range of sizes, shapes, formats, chemistries, and charge levels. They are among the most popular rechargeable batteries for portable electronic devices because of their outstanding energy densities, durability, and cost.
