| Description |
Lithiated transition metal oxides, namely, LiCo02, LiNi02,
and LiMn201, are usually employed as cathode material in
lithium ion batteries. However, among these materials, lithium
cobalt oxide (LiCo02) is most widely used in the majority
of commercial lithium ion cells owing to its ease of
synthesis and high reversibility.' Even though the theoretical
capacity of LiCoOz is around 273.8 mAh/g. practically only
0-.5 mol of lithium is extractable; thereby, it delivers only 137 mAh/g. Hence, to obtain higher capacities, one has to
charge the cells to high voltages (4.5 V),2 but such attempts
have failed to produce stable LiCoOz due to structural
changes3 during cycling.
