The energy storage device is fabricated by dispersing transition metal nanoparticles over a carbon-based support with a large specific surface area, and then, dispersing and resealing the nanoparticles over the support using lithium ions with strong reductive ability, so that the resealed metal particles are substantially particles dispersed and resealed over the support as particles having a size of less than 1 nanometer on the scale of atomic units. The supercapacitor is fabricated using the energy storage device. The energy storage device higher capacitance than before resealing of metal oxide. Since the resealed metal particles are those having a size of less than 1 nanometer on the scale of atomic units, interference between particles disappears to exhibit excellent cycle life characteristics of 100% maintained performance in even more than 100,000 cycles.

Abstract: Provided is an electrode material for an energy storage device, which comprises a metal organic framework, wherein an element having an unshared electron pair is doped to the organic linker of the metal organic framework. The electrode material for an energy storage device comprises a metal organic framework in which an element having an unshared electron pair is doped to the organic linker. The non-shared electron pair of the element doped to the electrode material is bound to high-order polysulfide to prevent the polysulfide from being transferred to lithium metal, thereby providing a good effect upon cycle characteristics and thus improving the cycle characteristics of an energy storage device, such as a lithium-sulfur battery. As a result, the metal organic framework having nitrogen doped thereto improves the cycle characteristics of an energy storage device, such as a lithium-sulfur battery, as a cathode thereof.
