Electrode-active anion-deficient non-stoichiometric lithium iron-phosphate, method for preparing the same, and electrochemical device using the same |
摘要 |
The invention provides an anion-deficient non-stoichiometric lithium iron phosphate as an electrode-active material, which is represented by the formula Li1−xFe(PO4)1−y, wherein 0<x≦̸0.15 and 0<y≦̸0.05. The invention provides a method for preparing said Li1−xFe(PO4)1−y, which comprises preparing a precursor of lithium iron phosphate; mixing said precursor with water under reaction conditions of 200˜700° C. and 180˜550 bar to produce lithium iron phosphate; and calcining, or granulating and calcining the resultant compound. The invention also provides electrochemical devices employing said Li1−xFe(PO4)1−y as an electrode-active material.
