摘要: The crystallinity of electrode materials affects the electrochemical performances of supercapacitors, typically for some transition metal oxides. The influence of crystallinity on the capacitive behavior of metal sulfides has not been well investigated so far. In this work, amorphous and crystalline CuCo 2 S 4 materials are prepared by anion− exchange and post− annealing. The annealing treatment under reasonable temperatures does not change the morphology and structure of CuCo 2 S 4 significantly. But, the degree of crystallinity of …
