Abstract: This disclosure describes a new method and device that lead to improved performance (in the areas of energy density, power density, and cycle life) of any sulfur or selenide based including their respective polysulfide/polyselenides battery configurations both for stationary and portable applications. A device capable of converting lower polysulfides/polyselenides to higher polysulfides/polyselenides (and vice versa) and trapping said compounds in a highly porous matrix is described. The device may be rechargeable. Catalytically-active materials such as bulk metal structures, thin films of metals, microporous/nanoporous structures of materials, and carbon composites of metals and their alloys can be used as current collectors, electrodes, or both.
