• Commercial lithium batteries use graphite as anode materials. Considering the high theoretical capacity of metallic Sb, in recent years some Sb-based intermetallic compounds have been investigated as potential anode materials for lithium ion batteries. The nanosized intermetallic compound NiSb2 was prepared by a solvothermal route and studied as a potential anode material for secondary lithium-ion batteries. The microstructure of the as-prepared NiSb2 powder was characterized by X-ray diffraction, transmission electron microscopy. The electrochemical performances of the NiSb2 electrode were investigated by galvanostatic charge and discharge cycling and by cyclic voltammogram. It was found that the nanosized NiSb2 electrode shows improved cycling behavior, especially in the initial cycles, compared to the micrometer sized NiSb2 prepared by a levitation-melting/ball-milling route.
