发明名称 Electrode materials for electrochemical cells
摘要 A lithiated metal phosphate material is doped by a portion of the lithium atoms which are present at the M2 sites of the material. The doped material has the general formula: Li1+xM1-x-dDdPO4. In the formula, M is a divalent ion of one or more of Fe, Mn, Co and Ni. D is a divalent metal ion which is one or more of Mg, Ca, Zn, and Ti. It is present in an amount represented by the subscript d which has a value ranging from 0 to 0.1. The portion of the lithium which is present at the M2 octahedral sites of the material is represented by the subscript x and is greater than 0 and no more than 0.07. Also disclosed are electrodes which incorporate the material as well as batteries, including lithium ion batteries, which include cathodes fabricated from the doped, lithiated metal phosphate materials.
