Cathode material examples

LiFePO4
Lithium Iron Phosphate

Lithium ions diffuse in 1 dimensional channels consist of chains of octahedral sites. It is a relatively economic cathode material, with iron being one of most abundant element on the earth.

LiCoO2
Lithium Cobalt Oxide

Lithium ions diffuse in 2 dimensional planes separated by CoO2 layers.It is the most widely used cathode material in consumer electronics since SONY first introduced it in 1991.
