Abstract
An activated carbon material derived, for example, by carbonizing and activating a non-lignocellulosic carbon precursor has a structural order ratio less than or equal to 0.08, and a nitrogen content greater than 0.2 wt. %. The activated carbon material can also have a volumetric capacitance greater than or equal to 70 F/cm, an area-specific resistance less than or equal to 0.1 ohm-cmand/or a specific surface area greater than 300 m/g, and is suitable to form improved carbon-based electrodes for use in high energy density devices.
