| 제목 | Hexagonal flower-like NiCo2O4 modifiedwith CoFe-layered double hydroxide compounds for supercapacitor electrodes |
| 초록 | Core-shell structure is stable and the ion diffusion distance is shortened. Because of the contact area between electrolyte and electrode increased, faraday reactionoccurs during charging, and has high reserve capacity. In this study, by changing the ratio of Co and Fe, to modify the hexagonal flower-like NiCo2O4 which was directly grown on Ni Foam, thereby, obtained the core-shell structure, and using for supercapacitor electrodes. We used hydrothermal method to synthesize the NiCo2O4 @ CoFe-layered double hydroxide (LDH) composites, in addition, the ratio of 1:2 for Co and Fe composite shows the synergy effect from the core-shell structure that the core is NiCo2O4 and the shell isCoFe-LDH. The composite prevented the aggregation of CoFe-LDH and provide richredox reaction, so that the composite has high specific capacitance and good stability. |
