ELECTRODE ACTIVE MATERIAL FOR ANION-DEFICIENT LITHIUM TRANSITION METAL PHOSPHATE COMPOUND, METHOD OF PREPARING SAME, AND ELECTROCHEMICAL DEVICE USING SAME |
| 摘要 |
The invention provides an anion-deficient lithium transition-metal phosphate as an electrode-active material, which is represented by the chemical formula Li 1-x M(PO 4 ) 1-y (0‰¤x‰¤0.15, 0<y‰¤0.05). The invention provides a method for preparing said Li 1-x M(PO 4 ) 1-y, which comprises preparing a precursor of lithium transition-metal phosphate; mixing said precursor with water under reaction conditions of 200 ˆ¼ 700°C and 180 ˆ¼ 550bar 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 Li 1-x M(PO 4 ) 1-y as an electrode-active material. |
