1. A material comprising:

  • carbon and sulfur;

    said carbon in the form of a porous matrix having nanoporosity in the form of nanopores and nanochannels having an average diameter between 1 nanometer and 50 nanometers; and

    said sulfur sorbed into a portion of said nanoporosity of said carbon matrix and in the form of nanoparticles having an external dimension that is greater than a minimal diameter of said nanoporosity where said nanoparticles are located such that said nanoparticles are trapped within said carbon matrix;

    said sulfur occupying more than 5% and less than 100% said nanoporosity such that there is free volume available within said nanoporosity.
