Surface and Interface Engineered Hierarchical Core/Shell Architecture for Ultrahigh Energy Density Hybrid Supercapacitors |
| 초록 |
Interfacial engineered spinel mixed transition metal oxides are promising pseudocapacitive electrode materials for high-performance supercapacitor (SC) applications due to their unique architecture as well as typical electronics properties. Herein, we propose the facile strategy to design a hierarchical core-shell architecture on nickel foam for enhancing the electrochemical performance. The interfacial engineered core-shell architecture offers reduced charge transfer resistance, rich electroactive sites and short ion diffusion path for redox reaction, leading to significantly improved performance. Consequently, the designed core/shell cathode has a large specific capacity along with good cycling stability, which is even better than that of previously reported metal oxide-based electrodes. Furthermore, the fabricated hybrid SC achieves an exceptional energy density with remarkable stability. This work resembles the great promise of surface or interface engineering for the development of low-cost cathode material for next-generation energy storage systems. |
