PRODUCTION OF AMORPHOUS VANADIUM PENTOXIDE POWDER AND LITHIUM SECONDARY BATTERY USING THIS AMORPHOUS VANADIUM PENTOXIDE AS POSITIVE ELECTRODE

摘要

PURPOSE:To efficiently produce amorphous vanadium pentoxide powder in a small-sized apparatus with high work efficiency and to provide a lithium secondary battery using this vanadium pentoxide as the positive electrode at a low cost. CONSTITUTION:Molten polycrystalline vanadium pentoxide or a molten mixture of polycrystalline vanadium pentoxide with other oxide is directly charged into pure water, etc., and the resulting colloidal oxide is dried to obtain amorphous vanadium pentoxide powder. This vanadium pentoxide is used as a positive electrode so as to obtain a lithium secondary battery. Since the molten starting material is simply charged into pure water, etc., various operations are made smooth.
