Lithium-ion batteries are promising energy storage technologies for portable electronic devices such as smart phones, camcorders, and laptops. Lithium vanadium pentoxide has been extensively studied as cathode material in lithium-ion batteries due to its ability for accept lithium ions. However, there is a disadvantage that structural instability occurs when a lot of lithium ions accepted. For this reason, we have replaced borate anion and synthesized carbon-coated lithium vanadium borate which may be expected enhancement of electrochemical properties and structural stability. We expected that the borate anion would lead to increase in structural stability and electric conductivity. The electrochemical properties of lithium vanadium borate were characterized by cyclic voltammetry (CV) measurement for reversibility of lithium extraction/inserting processes.
