  • 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.

  • Patent number: 9303329
    Abstract: Techniques disclosed herein include an electro-chemical deposition apparatus that provides an efficient circulation system, chemical management that provides reliable and uniform plating, and a configuration that provides short maintenance times and greater tool availability. Techniques include a processing tank containing an anolyte fluid, and one or more plating cells each having a catholyte fluid compartment with a circulation path that connects to a separate or remote catholyte reservoir. Thus, with such a configuration, a single pump can be used to flow catholyte (via manifolds) through one or more plating cells. Thus, with the catholyte reservoir maintained off board, instead of dumping catholyte over a weir into a reservoir, catholyte fluid—after flowing through a plating cell—is returned to the catholyte reservoir.

  • Publication number: 20140030636
    Abstract: In general, in one aspect, a graphene film is used as a protective layer for current collectors in electrochemical energy conversion and storage devices. The graphene film inhibits passivation or corrosion of the underlying metals of the current collectors without adding additional weight or volume to the devices. The graphene film is highly conductive so the coated current collectors maintain conductivity as high as that of underlying metals. The protective nature of the graphene film enables less corrosion resistant, less costly and/or lighter weight metals to be utilized as current collectors. The graphene film may be formed directly on Cu or Ni current collectors using chemical vapor deposition (CVD) or may be transferred to other types of current collectors after formation. The graphene film coated current collectors may be utilized in batteries, super capacitors, dye-sensitized solar cells, and fuel and electrolytic cells.
