    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.

    Abstract: Disclosed is a method for carbon coating on lithium titanium oxide-based anode active material nanoparticles. The method includes (a) introducing a lithium precursor solution, a titanium precursor solution and a surface modifier solution into a reactor, and reacting the solutions under supercritical fluid conditions to prepare a solution including nanoparticles of an anode active material represented by Li4Ti5O12, (b) separating the anode active material nanoparticles from the reaction solution, and (c) calcining the anode active material nanoparticles to uniformly coat the surface of the nanoparticles with carbon. Further disclosed are carbon-coated lithium titanium oxide-based anode active material nanoparticles produced by the method. In the anode active material nanoparticles, lithium ions are transferred rapidly. In addition, the uniform carbon coating ensures high electrical conductivity, allowing the anode active material nanoparticles to have excellent electrochemical properties.
