with R-3m as space group. Morphological properties have been investigated by using characterization tool such as FESEM, which confirms the formation of composite material. Thermal properties have been characterized by DSC/TG measurements. Electrochemical performance of the material is under study. CNTs helped in increasing the cycle life of the material when cycled in the voltage range of 4.6-2.8V at a cycling rate of 0.2 mA/cm

, however the impedance is found to be higher in case of the composite material compared to the pristine nano-sized LNMC.
