Hydrothermal Carbonization of Abundant Renewable Natural Organic Chemicals for High-Performance Supercapacitor Electrodes

Year: 2011

Type: article

Abstract: Cellulose, potato starch, and eucalyptus wood saw dust were transformed into porous carbons with micropore surface areas of up to 2387 m2/g. The specific capacitance of the produced carbons approaches 236 F/g (100 F/cc) when measured in a symmetric configuration in an organic electrolyte. Charge-discharge tests showed excellent capacitance retention with capacitance of up to 175 F/g at an ultra-high current density of 20 A/g.
