Abstract

A method for producing an activated carbon material includes heating a non-lignocellulosic carbon precursor to form a carbon material and reacting the carbon material with steam to form an activated carbon material. The activated carbon material is suitable to form improved carbon-based electrodes for use in high energy density devices.
