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.
