Novel cathode material having a shell and core structure has been developed for Lithium Ion batteries. This study essentially involves the electrochemical performance and thermal stability of core-shell material and verifies the effects of the shell and core separately. It was observed that the capacity obtained of the shell was about 145mAh/g and that of core was about 190 mAh/g. The overall capacity of the core-shell composite electrode was 175 mAh/g. Electrochemical impedance spectroscopy was used to explain the possible interfacial phenomena occurring within the material during lithium intercalation-deintercalation processes. Thermal studies were also investigated using Differential Scanning Calorimeter (DSC).
