Lithium Ion Battery

Overview
The lithium ion battery is a type of rechargeable battery which uses lithium cobalt oxide as anode and carbon as cathode. The lithium ions move from the negative electrode to the positive electrode during discharge, and they migrate from the positive electrode to negative electrode when charging.

Applications
Lithium ion batteries are widely used for mobile phone, digital camera, laptop computers, DVD player, MP4, etc. They are also growing in popularity for military and aerospace applications.
