초록/요약
Non-stoichiometric lithium vanadium oxide, Li1.1V0.9O2, has been successfully synthesized through solid-state reaction, which involves two-separate high temperature calcinations procedure. After particle has been synthesized, X-ray Diffraction was used to confirm its crystallinity. Its surface structural characterization has been studied with scanning electron microscope. Also, Li1.1V0.9O2’s surface has been coated with carbon, using sucrose as carbon-source. Its crystal characterization has been determined by x-ray diffraction, while the carbon’s structure has been determined by Raman spectrometry. Carbon-coated Li1.1V0.9O2’s surface structural characteristics have been studied with scanning electron microscope, and transmission electron microscope. Bare Li1.1V0.9O2 and carbon-coated Li1.1V0.9O2’s electrochemical characterization has been determined for applications in lithium-ion rechargeable batteries. Both powders’ electrochemical characterization has been determined by using cyclic voltammetry, electrochemical impedance spectroscopy, and galvanostatic charge/discharge cycle, in a coin-type half-cell configuration.
