Ultrathin hierarchical porous carbon nanosheets for high-performance supercapacitors and redox electrolyte energy storage

The design of advanced high-energy-density supercapacitors requires the design of unique materials that combine hierarchical nanoporous structures with high surface area to facilitate ion transport and excellent electrolyte permeability. Here, shape-controlled 2D nanoporous carbon sheets (NPSs) with...
