3D Carbon Frameworks for Ultrafast Charge/Discharge Rate Supercapacitors with High Energy-Power Density

Nano-Micro Letters, 2020
3D carbon frameworks (3DCFs) constructed by interconnected nanocages show a high specific surface area, hierarchical porosity, and conductive network. The deoxidization process removed most of surface oxygen-containing groups in 3DCFs that leads to fast ...
