This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived VersionsPorous carbon-based supercapacitors have become an essential energy storage technology. Establishing a sustainable energy-efficient economy demands novel synthesis routes for the formation of better performing porous carbons from readily available and renewable low-cost materials. Hydrothermal carbonization is an environmentally friendly, low-cost, low-temperature carbon synthesis route that produces non-porous carbons. Therefore, it has never been utilized for surface-area sensitive applications, such as supercapacitor electrode production. Here we demonstrate, for the first time, that hydrothermal carbonisation followed by activation allows very efficient transformation of abundant natural materials into microporous carbons with unusually high surface area of interconnected micropores for outstanding performance in supercapacitors. Cellulose, potato starch and eucalyptus wood saw dust were transformed into porous carbons with micropore surface area up to 2387 m2/g. Application of the produced carbons in supercapacitors based on a 1 M tetraethylammonium tetrafluoroborate solution in acetonitrile showed potential for ~100% enhancement in energy storage capacity of commercial devices. Specifically, the cyclic voltammetry showed the specific capacitance approaching 236 F/g (100 F/cc), when measured in a symmetric configuration in this organic electrolyte. Charge-discharge tests showed excellent capacitance retention with capacitance up to 175 F/g at an ultra-high current density of 20 A/g. The combination of very high specific and volumetric capacitance and good rate capability of the hydrothermally synthesized porous carbons is unmatched by state-of-the art activated carbons, carbon nanotubes, carbon onions and graphene.This work was partially supported by the AFOSR under grant # FA9550-09-1-0176.
