LiFe(MoO 4 ) 2 microcrystals have been fabricated via a facile sol–gel driving process. The obtained LiFe(MoO 4 ) 2 microcrystalsare characterized through X-ray diff raction, thermal analysis, scanning electron microscope, transmission electronmicroscope and high resolution transmission electron microscope. The results demonstrate that the as-synthesized microcrystalspossess triclinic structure and exhibit uniform particle size of 1–2 μm. When served as anode material for lithiumion batteries, LiFe(MoO 4 ) 2 microcrystals display a very high specifi c capacity of 925 mAh g −1 at a current rate of 1 C after500 cycles and a high retention rate of 88%, showing superior electrochemical performance.
