Abstract :
CNT/LiNi0.33Mn0.33Co0.33O2 nanocomposite electrode material was fabricated for Lithium Ion Battery. Sol-Gel synthesis has been used to synthesize the nano-sized pristine LiNi0.33Mn0.33Co0.33O2 (LNMC). CNT/LiNi0.33Mn0.33Co0.33O2 nanocomposite has been synthesized by using low temperature dispersion method. Structural characterization of the material has been performed by using X-ray diffraction, which shows the formation of single phase LiNi0.33Mn0.33Co0.33O2 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/cm2, however the impedance is found to be higher in case of the composite material compared to the pristine nano-sized LNMC.
