摘要： 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.

摘要： A silicon nitride layer is provided on an uppermost surface of a graphene layer and then a hafnium dioxide layer is provided on an uppermost surface of the silicon nitride layer. The silicon nitride layer acts as a wetting agent for the hafnium dioxide layer and thus prevents the formation of discontinuous columns of hafnium dioxide atop the graphene layer. The silicon nitride layer and the hafnium dioxide layer, which collectively form a low EOT bilayer gate dielectric, exhibit continuous morphology atop the graphene layer.
