Synthesis of cobalt-manganese layered double hydroxide/graphene composites and their capacitance analysis for supercapacitor electrodes |
| 초록 |
Layered double hydroxides (LDHs) are a large class of double metal materials that are consisted of divalence and trivalence cations octahedrally surrounded by hydroxyls. LDHs can offer improved electrochemical properties because it has tunable composition. LDH layers provides a higher stability for effective valence interchange and charge transfer. In this study, we synthesized CoMn-LDH/RGO composite using hydrothermal method. Electrochemical performances were examined by cyclic voltammetry (CV) and galvanostatic charge-discharge curves. As the CoMn-LDH not only offer pseudo-capacitance but also prevent restacking of reduced graphene oxide, composites showed highly improved specific capacitance than pure each components. |
