摘要: 采用高温熔盐法合成了镁二次电池正极材料Cu₂Mo₆S_8-nSe_n(n=0,0.5,1.5),以X射线衍射(XRD),扫描电子显微镜(SEM),循环伏安测试(CV),恒电流充放电测试,电化学阻抗(EIS)为研究手段表征了材料的结构和电化学性能。XRD和SEM测试结果表明,Cu₂Mo₆S_8-nSe_n正极材料仍然是Chevrel相结构,材料结晶良好,粒径小,由于Se原子掺入,使得点阵常数变大,更有利于镁离子嵌入/脱嵌。电化学测试表明,掺入Se原子,材料比容量略有提升,达到103.5 mAh·g^-1;循环伏安曲线在0.5～0.8 V区域的峰形发生了显著变化,曲线上氧化还原峰对称性更好;材料的室温循环性和可逆性提高。

Abstract: The Chevrel Phase materials Cu₂Mo₆S_8-nSe_n (n=0,0.5,1.5) were synthesized by molten salt methods. Their crystal structures and the electrochemical properties were studied by a combination of X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry test (CV), galvanostatic charge-discharge test and electrochemical impedance spectroscopy (EIS). XRD analysis showed that Se-substituted Cu₂Mo₆S_8-nSe_n was still Chevrel Phase, however the lattice parameters became larger, and SEM pictures viewed the particle size was small. The studies of the electrochemical properties suggested that the shape of voltammetric peaks in the region 0.5～0.8 V changed, the steady specific capacity increased to 103.5 mAh·g^-1 and the cycling performance were improved because of Se substituted in Cu₂Mo₆S8. All these proved the reversible intercalation of Mg ions into these hosts were facilitated.
