通过改变溶剂热反应的液体环境，探究了所制备超级电容器电极材料CuCo₂S₄的形貌、粒径以及作为电极材料的比容量。利用XRD、SEM等测试手段对所制备的活性材料CuCo₂S₄的形貌和粒径进行分析，利用循环伏安测试（CV）、恒电流充放电测试（GCD）和电化学阻抗（EIS）等测试手段对电极的电化学性能进行分析。结果表明，丙三醇溶剂环境比乙二醇溶剂环境所制备CuCo₂S₄的粒径更小、质量比容量更大，同时CuCo₂S₄颗粒粒径随着油浴保温时间延长而变大。在溶剂环境中加入丙三醇、油浴时间为10 h条件下制备的CuCo₂S₄电极材料具有最优的电化学性能，在电流密度为2 A/g时，质量比容量可达659 F/g。

Morphology and particle size of CuCo₂S₄,and its specific capacitance as electrode material are investigated through changing the liquid environment of solvent thermal reaction.Morphology and particle size of the prepared CuCo₂S₄ are analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM),and the electrochemical performances are characterized by cyclic voltammetry (CV),current charge and discharge test (GCD) and electrochemical impedance (EIS).It is indicated that CuCo₂S₄ prepared in a glycerol solvent environment has a smaller particle size and a larger specific capacitance than that prepared in an ethylene glycol solvent environment.The particle size of CuCo₂S₄ increases with the prolongation of oil bath time.CuCo₂S₄ that is prepared in a glycerol solvent environment for 10 h of oil bath holds the best electrochemical performances,it can achieve a specific capacitance of 659 F·g^-1 at a current density of 2 A·g^-1.
