Designing of high-performance cathode materials for lithium ion batteries is emerging as a major task in view of the wide range of applications ranging from cell phones to electric vehicles and also in medical equipment. Usually, lithiated transition metal oxides, namely, LiCoO2, LiNiO2, and LiMn2O4, are employed as cathode materials. However, among these mentioned materials, lithium cobalt oxide (LiCoO2) is the most widely used in the majority of commercially available lithium ion batteries owing to its ease of synthesis and high reversibility.1 In view of the advantages associated with LiCoO2, the maximum attainable practical capacity is only around 137 mAâh/g when cycled in the voltage range 3-4.25 V, although the theoretical capacity is as high as 273.8 mAâh/g. Therefore, to obtain higher capacities, one has to charge the cells to high voltages (4.5 V).2
