Abstract

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.
