  • ELECTRODE-ACTIVE ANION-DEFICIENT LITHIUM TRANSITION-METAL PHOSPHATE, METHOD FOR PREPARING THE SAME, AND ELECTROCHEMICAL DEVICE USING THE SAME
    Publication number: 20120021288
    Abstract: The invention provides an anion-deficient lithium transition-metal phosphate as an electrode-active material, which is represented by the chemical formula Li1?xM(PO4)1?y (0?x?0.15, 0?y?0.05). The invention provides a method for preparing said Li1?xM(PO4)1?y, which comprises preparing a precursor of lithium transition-metal phosphate; mixing said precursor with water under reaction conditions of 200˜700 and 180˜550 bar to produce an anion-deficient lithium transition-metal phosphate; and calcining, or granulating and calcining the resultant compound. The invention also provides electrochemical devices employing said Li1?xM(PO4)1?y as an electrode-active material.
