Structural and Electrical conductivity studies of LiMnBO3 Nanoparticles

Li-ion batteries to play even more important roles in hybrid electrical vehicles (HEVs), electrical vehicles (EVs), plug-in hybrid vehicles (PHEVs), and smart grid systems area [1-3]. However, they currently fail in meeting the demands dictated by powering of large-scale storage systems for renewable energy sources. Hence, it is necessary to develop Li-ion batteries with higher energy densities. Cathode materials to play an important role among the components of Li-ion batteries to operate at high voltage and deliver high energy and high power densities. Lithium manganese borate (LiMnBO3) powders were synthesized by a sol-gel process. The structural coordination of LiMnBO3 was investigated by FTIR analysis. From X-ray diffraction patterns, confirms the formation of the nanocrystalline pure hexagonal isotypic phase of the LiMnBO3 at 650 degrees C. The observed SEM micrographs of the LiMnBO3 sample showed the formation of agglomerated spherical shape particle morphology of the LiMnBO3 sample is confirmed by the SEM result. The electrical conductivity of LiMnBO3 sample was evaluated by analysing the measured impedance data and it was found to be 1.37 x 10(-8) S cm(-1) at room temperature. Detailed results will be presented and discussed.
