LiFePO4 co-doping with Mg and Co ions was synthesized by a solid state reaction method.The structure and electrochemical properties of the prepared LiFe0.99Mg0.005Co0.005PO4 were investigated by X-ray diffraction (XRD), galvanostatic charge-discharge experiment and cyclic voltammograms (CV).The specific discharge capacity of LiFePO4 co-doping with Mg and Co ions reached 147mAhg-1 at 0.1C and 133 mAhg-1 at 1C.The results of CV showed that the reversibility of lithium extraction/insertion in LiFePO4 can be promoted by (Mg2+, Co4+) multiple-ion doping.
