Lithium Cobalt Oxide – LiCoO2

In LiCoO2, lithium ions diffuse in 2 dimensional planes. It is the most widely used cathode material in consumer electronics since SONY first introduced it in lithium ion batteries in 1991.

In LiCoO2, lithium ions occupy octahedral sites (shown in yellow in the animation) in the 2 dimensional lithium diffusion planes between the CoO2 layers. Lithium ions move by hopping through neighbouring tetrahedral sites (shown in blue in the animation). Thus, lithium ions diffusion in LiCoO2 is 2 dimensional.
