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.

LFP

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.
LCO

LiMn2O4
Lithium Manganese Oxide

Lithium ions diffuse in 3 dimensions in spinel LiMn2O4 by hopping between tetrahedral sites via intermediate octahedral sites.
LMO
