  • Patent number: 10164239
    Abstract: Disclosed is an energy storage device based on metal oxide nanocrystals resealed through lithiation, and a supercapacitor using the same. 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.
