Claims27
An electric capacitor, comprising at least a first electrode surface, which electrode surface comprises a plurality of nanofibers, wherein a density of the plurality of nanofibers ranges from about 0.11 nanofiber per square micron or less to at least about 1000 nanofibers per square micron, from about 1 nanofiber per square micron or less to at least about 500 nanofibers per square micron, from about 10 nanofibers per square micron or less to at least about 250 nanofibers per square micron, or from about 50 nanofibers per square micron or less to at least about 100 nanofibers per square micron.
An electric capacitor, comprising at least a first electrode surface, which electrode surface comprises a plurality of nanofibers, wherein a density of the members of the plurality of nanofibers increases the surface area of the first electrode surface at least 1.5 times to at least 100,000 times or more, at least 5 times to at least 75,000 times or more, at least 10 times to at least 50,000 times or more, at least 50 times to at least 25,000 times or more, at least 100 times to at least 10,000 times or more, or at least 500 times to at least 1,000 times or more greater in comparison to an area of electrode surface without nanofibers, which area comprises a substantially equal footprint.
An electric capacitor, comprising at least a first electrode surface, which electrode surface comprises a plurality of nanofibers, wherein the farad capacity of the capacitor comprises from about at least 1.5 times to at least 100,000 times or more, at least 5 times to at least 75,000 times or more, at least 10 times to at least 50,000 times or more, at least 50 times to at least 25,000 times or more, at least 100 times to at least 10,000 times or more, or at least 500 times to at least 1,000 times or more greater in capacity in relation to a capacitor having an electrode surface of substantially equal footprint but not comprising a plurality of nanofibers.
A capacitor comprising a supporting substrate having at least a first electrode surface, a nanostructured thin film layer comprising alumina or aluminum deposited on at least a region of the surface, and a hydrophobic coating deposited on the film layer.
