Abstract

We demonstrate an aqueous supercapacitor based on self-standing, porous, hydrophilic, and 26 μm thick activated carbon nanofoam. The device delivers areal (volumetric) capacitance of 95.4 mF/cm2 (18.3 F/cm3) at 2 mA with retention of 103% at 20 mA and achieves 1V voltage compared to pristine and annealed ones.
