What Is A Lithium-ion Battery?

A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.

Lithium-ion batteries are common in home electronics (such as iRobot Roomba cleaning robot). They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density and low self-discharge. LIBs are also growing in popularity for military, battery electric vehicle and aerospace applications.

Research areas for lithium-ion batteries include life extension, energy density, safety, cost reduction, and charging speed, among others.
