For LCO electrode chemistry, doping with elements like lanthanum and aluminium has been observed to increase the capacity to almost the capacity limit . Other elements like Mg and Mn when doped into LCO have been observed to improve the cycling performance . Magnesium diffuses into the LCO crystal structure and stabilises the lattice thus preventing undesired phase transformations at high potentials. Surface coatings such as ZrO2 have been explored as they improve the cycle life and rate capability at high voltages . The surface coating acts as a protective layer and prevents LCO from coming in direct contact with the electrolyte thus preventing its oxidation and subsequent cobalt ion dissolution. The coatings also suppress resistance caused due to the intercalation and de-intercalation of lithium ions. Coatings have also been studied to decrease the activation energy at the electrode-electrolyte interface, thereby positively affecting the kinetics of lithium-ion transfer. Surface engineering techniques and the growth of Al2O3 and Al-W-Fluoride on LCO have been studied to increase cyclic stability .
