摘要：
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.
