Abstract:

LiFe(MoO4)2 was synthesized by solid state reaction and its structural and magnetic property were investigated by Xray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and superconducting quantum interference device (SQUID). Furthermore, its
 electrochemical properties were tested between 3.0 V and 1.0 V. The electrochemical tests show that, as a positive electrode material, LiFe(MoO4)2 demonstrates good cycle performance with a reversible capacity of 200 mA·h/g and high coulombic efficiency of 98.5%, respectively.

Key words: lithiumion battery, LiFe(MoO4)2, magnetic property, electrochemical property
