Multi-component Carbon-Based Composites Containing High Crystallinity NiBDC As High-Performance Electrodes for Supercapacitors.
CHEMICAL COMMUNICATIONS(2023)
摘要
Herein, we propose a strategy combining in situ sol-gel hydrothermal growth and annealing treatment for preparing multi-component carbon-based composites with high crystallinity of NiBDC (C-Ni/NiO/NiBDC). The C-Ni/NiO/NiBDC can be used by both positive and negative materials to build a supercapacitor that shows superior capacitance over the wide potential range of 0-1.8 V, resulting from the high crystallinity of NiBDC and synergistic effect of NiBDC, Ni and NiO, as well as their mutual intimate interfacial contact.
