摘要
Li-storage intermetallic compound FeSb2 was prepared by solvothermal method and was studied as a promising anode material for secondary lithium-ion batteries. The as-prepared powder was characterized by X-ray diffraction （XRD） and field emission scanning electron microscopy （FESEM）. The electrochemical Li-storage performances of this intermetallic anode were evaluated in a two-electrode cell Li/LiPF6 （EC＋DMC）/FeSb2. It was found that the particle size of FeSb2 powder is in nanoscale and this intermetallic anode exhibited enhanced cycling behavior comparing to its microscaled counterpart prepared by levitation-melting/ball-milling route.
