Abstract

A series of nanocomposite LiFe(1-2x)ZrxPO4/C (x = 0.01,0.02, 0.03, 0.04, 0.06) were prepared by carbon thermal reduction method. With this strategy, the Li3PO4 impurity phase can be obviously reduced in the Zr-doped samples and the electrochemical performance is obviously improved by Zr doping compared with the undoped one. The best electrochemical performances were observed in LiFe(0.92)Zr(0.04)PO4/C as well as good cycle stability.
