| 摘 要： | 采用悬浮熔炼方法合成了FeSb合金，并研究了其作为锂离子电池负极材料的电化学性能。结果发现，虽然FeSb的容量低于纯锑。但其循环稳定性要优于纯锑。本实验采用恒电流间隙滴定技术(GITT)测定了在嵌锂过程中锂离子的化学扩散系数，在30℃时，该值在10^-12cm^2s^-1～10^-10cm^2s^-1范围内。

| Abstract: | FeSb alloy was synthesized by levitation melting. The electrochemical properties of the alloy were investigated as the candidate for the anode material of secondary Li-ion batteries. It is found that although the FeSb alloy shows lower specific capacity than pure Sb, it exhibits improved cycling stability. The composition dependence of the chemical diffusion coefficient DLi was determined by the galvanostatic intermittent titration technique (GITT). The value of DLi of FeSb alloy is in the range of 10-12 cm2s-1～10-10 cm2s-1 at 30℃. |
