LiFe1-x(Ni0.98Co0.01Mn0.01)(x)PO4/C (x = 0.01, 0.03, 0.05, 0.07) is prepared by using spent electroless nickel plating solution as a raw material. The mechanism of the reaction is investigated by the analyses of thermogravimetric and differential scanning calorimeter (TG/DSC) and X-ray diffraction (XRD). It is found that the formation of LiFe1-x(Ni0.98Co0.01Mn0.01)(x)PO4/C starts at 300 degrees C, and above 500 degrees C, the product can be ascribed to LiFe1-x(Ni0.98Co0.01Mn0.01)(x)PO4/C. The structure, morphology and electrochemical properties of the samples are characterized by XRD, scanning...
