摘要：
The spherical-like ZnSe is synthesized via a simple hydrothermal method in which Zn(NO3)(2)center dot 6H(2)O and Na2SeO3 are employed as Zn and Se sources, respectively. The diameter of ZnSe spheres is in the range of 0.5-1 mu m. Meanwhile, the obtained ZnSe is used as an electrode material for lithium-ion batteries (LIBs). The ZnSe spheres display outstanding electrochemical performance with an initial discharge capacity of 960 mA h g(-1) and a high reversible capacity of 433 mA h g(-1) after 50 cycles at 100 mA g(-1). The electrochemical results indicate that the spherical-like ZnSe is a promising electrode material for LIBs. (C) 2015 Elsevier B.V. All rights reserved.
