Appl. No.:

14/457723

Inventors:

- Bethesda MD, US
Rebecca Schwartz - Chester Springs PA, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

H01G 11/70
H01G 11/86
H01G 11/68

Abstract:

An improved supercapacitor includes a first and second electrode with each electrode made at least in part from a highly-porous electrically conductive material, a insulative separator separating the electrodes; a first electrically conductive current collector in physical and electrical contact with the first electrode; and a second electrically conductive current collector in physical and electrical contact with the second electrode, wherein at least one current collector is configured to have multiple separate portions with each portion having a current capacity that varies as a function of current passing through during capacitive operation.

Abstract:

Three-dimensional (3D) graphene nanoribbons and methods for fabricating 3D graphene nanoribbons that may readily function as solenoid windings and the like. In one embodiment, a method of fabricating a 3D graphene nanoribbon () may include coating a side surface (A) of a 3D insert () with a metal () appropriate for graphene growth thereon. The method may also include growing a layer () of graphene directly on the metal coating. The method may also include removing a strip of the graphene layer and metal coating () to expose the side surface (A) of the insert () while leaving a line () of graphene on metal winding around the insert () and extending continuously from a first end (A) of the line () to a second end (B) of the line ().

Abstract:

Apparatuses and systems for removing water vapor from a gas stream and for providing water purification, recovery and/or concentration. The apparatuses and systems employ a graphene oxide or a perforated graphene monolayer membrane to separate liquid water molecules and/or water vapor molecules from gasses, liquids, and other substances such as a wet muck or an aqueous sample. In one embodiment, an apparatus for removing water from a gas or liquid stream includes a first lumen, a second lumen, and a graphene oxide membrane separating the first lumen from the second lumen. Water molecules within a humid gas or liquid stream introduced into the first lumen pass through the graphene oxide membrane into a dry gas stream introduced into the second lumen.
