▎ 摘　　要

In this work, we synthesize a high performance FeSe2-C/rGO (reduced graphene oxide) anode material for lithium-ion batteries. Benefiting from the advantages of using Fe-MOG (Metal organic gel) as precursor and the addition of rGO sheets, the rodlike FeSe2 is obtained, and the graphene not only limit the size of FeSe2 rods to smaller, but improve the conductivity. Cyclic voltammetry, galvanostatic discharge/charge and electrochemical impedance spectroscopy are utilized to examine the electrochemical characteristic of FeSe2-C/rGO anode. The cell display an extremely stable electrochemical properties during the redox reaction process and superior rate performance. Particularly, the discharge capacity of FeSe2-C/rGO anode is 917.6 mA h g(-1) after 100 cycles at 100 mA g(-1) with the coulombic efficiency of 99%, which is slightly higher than the initial discharge capacity in cycling. Besides, the FeSe2-C/rGO anode material exhibit the best cyclability compared to FeSe2-C, Fe2O3-C/rGO and FeS2-C/rGO anode material, which are prepared by the analogous synthesis process.
