An electrode material having carbon and sulfur is provided. The carbon is in the form of a porous matrix having nanoporosity and the sulfur is sorbed into the nanoporosity of the carbon matrix. The carbon matrix can have a volume of nanoporosity between 10 and 99%. In addition, the sulfur can occupy between 5 to 99% of the nanoporosity. A portion of the carbon structure that is only partially filled with the sulfur remains vacant allowing electrolyte egress. In some instances, the nanoporosity has nanopores and nanochannels with an average diameter between 1 nanometer and 999 nanometers. The sulfur is sorbed into the nanoporosity using liquid transport or other mechanisms providing a material having intimate contact between the electronically conductive carbon structure and the electroactive sulfur.
