KOH-activated micrometer-thick amorphous carbon nanofoam as a binder-free supercapacitor electrode with high-rate performance
We demonstrate an aqueous supercapacitor based on self-standing, porous, hydrophilic, and 26-μm-thick activated carbon nanofoam. The device delivers an areal (volumetric) capacitance of 95.4 mF/cm<sup>2</sup> (18.3 F/cm<sup>3</sup>) at 2 mA with retention of 103% at 20 mA and achieves a voltage of 1 V, superior compared to pristine and annealed examples.
