    Abstract: Embodiments of the claimed invention are directed to a device, comprising: an anode that includes a lithiated silicon-based or lithiated carbon-based material or pure lithium metal or metal oxides and a sandwich-type sulfur-based cathode, wherein the anode and the cathode are designed to have porous structures. An additional embodiment of the invention is directed to a scalable method of manufacturing sandwich-type Li—S batteries at a significantly reduced cost compared to traditional methods. An additional embodiment is directed to the use of exfoliated CNT sponges for enlarging the percentage of sulfur in the cathode to have large energy density.

    Abstract: Disclosed are non-noble element compositions of matter, structures, and methods for producing the catalysts that can catalyze oxygen reduction reactions (ORR). The disclosed composition of matter can be comprised of graphitic carbon doped with nitrogen and associated with one or two kinds of transition metals. The disclosed structure is a three dimensional, porous structure comprised of a plurality of the disclosed compositions of matter. The disclosed structure can be fashioned into an electrode of an electrochemical cell to serve as a diffusion layer and also to catalyze an ORR. Two methods are disclosed for producing the disclosed composition of matter and structure. The first method is comprised of two steps, and the second method is comprised of a single step.
