    Abstract: Embodiments of the claimed invention are directed to a device, comprising: an anode that includes a lithiated silicon-based material and a sulfur-based cathode, wherein the anode and the cathode are designed to have mesoporous structures. In certain embodiments, the sulfur-based cathode is a mesoporous carbon structure comprising sulfur within the mesopores. A further embodiment of the invention is directed to a device comprising a semi-liquid lithium-sulfur battery comprising a lithium anode and a sulfur cathode. In certain embodiments, the sulfur cathode comprises a liquid catholyte, which is housed within a reservoir that is a carbon nanotube sponge. An additional embodiment of the invention is directed to a method for producing a lithiated silicon anode and a sulfur-based cathode.

    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.
