3D Nitrogen-enriched graphene porous graphene hydrogel for high-performance supercapacitor

3D interconnected porous nitrogen-enriched graphene (NG) hydrogel was fabricated through ethanediamine as reducing and doping agent. The 3D porous structure of the NG enhances the accessibility to ion diffusion. Notably, when the NG material works as binder-free electrode, it achieves a high specifi...
