  • Recycling method of olivine-based cathode material for lithium secondary battery, cathode material fabricated therefrom, and cathode and lithium secondary battery including the same
    Patent number: 9643846
    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.
