| Abstract |
Recently, lithium transition metal borates, LiMBO3 (M = Mn, Fe or Co), have been studied by many research groups due to low weight of (BO3)3-, relatively weak B-O bond, and high theoretical capacity. Its weaker B-O bond makes fast lithium ion diffusion. However, it has limitation because of their low ionic and electronic conductivities, which is revealed relatively low reversible capacity. Therefore, LiV2BO5 (LVBO) has been studied to improve operating potential, because multiple valence states of vanadium element can provide a high theoretical energy density. Also, fluorine doping in LVBO has been attempted to synthesis by sol-gel method. The morphology and composition of materials have been identified with scanning electron microscope and X-ray diffraction. The electrochemical properties are characterized by using galvano-static charge/discharge and cyclic voltammetry measurements. The optimum doping ratio in LVBO is still under study with electrochemical properties. |
