In situ thermal treatment of metal organic framework (MOFs) is becoming a popular technique to construct uniform and similar carbon-based composites with excellent performance in many research fields such as catalysts, storages, and so on. In this study, cobalt and carbon composites derived from a zeolitic imidazolate framewrok (ZIF) are selected as a cathode of a lithium sulfur battery. The obtained products with polyhedron structure and sulfur are composed of a cathode. The temperature of thermal treatment is carefully optimized, and the effects of it on morphology and electrochemical performances are investigated. It is very interesting that the results of this study are indicated differeneces along the temperature of thermal treatment. In order to prove this results, electrochemical properties were characterized by cyclic voltammetry and Galvanostatic charge-discharge experiment by assembling CR-2016 coin cells. |
