Abstract: There is provided a preparation method of a sodium vanadium oxide-based (Na1+xV1-xO2) anode material for a sodium ion secondary battery synthesized by mixing particles of precursors such as sodium carbonate (Na2CO3) and vanadium oxide (V2O3) and pyrolyzing a mixture in a mixed gas atmosphere composed of 90 mol % of nitrogen gas and 10 mol % of hydrogen gas through a solid-state reaction. The sodium vanadium oxide-based anode material prepared according to the present invention shows a small change in volume caused by an initial irreversible capacity and continuous charge/discharge reactions, and thus it is useful for providing a next-generation sodium ion secondary battery having stable charge/discharge characteristics and cycle performance.

Abstract: The present invention relates to a method for recycling LiFePO4, which is an olivine-based cathode material for a lithium secondary battery. The present invention is characterized in that a cathode material including LiFePO4 is synthesized using, as precursors, amorphous FePO4.XH2O and crystalline FePO4.2H2O (metastrengite) obtained by chemically treating LiFePO4 as an olivine-based cathode material for a lithium secondary battery, which is produced from a waste battery. Since a cathode fabricated from the LiFePO4 cathode material synthesized according to the present invention does not deteriorate the capacity, output characteristics, cycle efficiency and performance of the secondary battery and the cathode material of the lithium secondary battery may be recycled, the secondary battery is economically efficient.
