The LCO battery chemistry has been restricted to use in small-scale applications like portable electronics and is not suitable for electric vehicle and hybrid electric vehicle applications . Primarily because of its high cobalt content which makes it costly. It has poor chemical stability after extraction of 50% of all the lithium (Li0.5CoO2). Hence, the practical reversible capacity is only around 130 mAh/g though the theoretical capacity is about 274 mAh/g. Extraction of lithium greater than 50% leads to the oxidation of O 2-leading to the evolution of oxygen gas and the breakdown of the structure . This happens due to the overlapping of the t 2g band of the cobalt ions with the 2p band of oxygen ions . Another problem associated with LCO chemistry is that when the cut-off voltage is increased beyond 4.2V, cobalt undergoes dissolution into the electrolyte due to phase transformation effects. This leads to strains and the development of micro cracks increasing inter-facial resistance and leading to chemical degradation of the battery electrode. Though LCO gives us a high discharge voltage it suffers from disadvantages like high cost, poor rate capability and poor thermal stability which restricts its use in high-load applications.
