20090136834 (05/28/2009)
Carbon monofluoride, conductivity additive, and
Coowar, Fazlil Ahmode;
polyvinylidene fluoride binder were used to create a
Blackmore, Paul David/
paste and subsequently cast on aluminum foil to
Qinetiq Limited, UK
create cathode.

20080287607 (11/20/2008)
Precursor polyacrylonitrile dispersed in
Lien Tai Chen; Shu-Hui
dimethylforamide or dimethylacetamide undergoes
Cheng; Tun-Fun Way; Tzu
nanospinning process. Spun fibers are stabilized at
Hsien Han/Industrial
270°C, and activated through heating at 1000°C.
Technology Research
Evaluation of capacitance using aqueous electrolyte
Institute
yields >300 F/g.

20100134954 (10/25/2008)
Supercapacitor electrode is constructed of mesoporous
Chris Wright; Jennifer
metal (nickel and its oxides, hydroxides, and
Sweeney; Daniel Peat;
oxyhydroxides) or metal compound using carbon;
Phillip Andrew Nelson/
volume ratios are preferably 15:1 to 50:1. Capacitance
Nano-Tecture Ltd.
of Ni electrode measured at current density of 2092
mA/cm 2 to be 1635 F/cm 3 . Capacitance of carbon
electrode measured at same current density was 106
F/cm 3 .
17
20080232028 (09/25/2008)
Carbon nanosheet of <2 nm thickness and specific
Zhao Xin/College of
surface area between 1000 and 2600 m 2 /g attached to
William & Mary, U.S.
smooth carbon fibers by thermal chemical deposition
or microwave plasma chemical deposition. Composite
is then used as electrode in full cell supercapacitor.
18
20080218939 (09/11/2008)
Nickel or gold nanowire electrode between 0.02 and 0.2
Marcus, Matthew S.; Gu,
μm wide is created using porous alumina or silica
Yuandong/Honeywell
membrane. Dissolving membrane leaves metal
International, U.S.
nanowires to be used as electrode.
19
20080010796 (01/17/2008)
Functionalized CNTs are attached to metal substrate
Pan, Ning; Du, Chunsheng/
(nickel, copper, aluminum, gold, or platinum) by
University of
electrophoretic deposition after dispersion and
California, U.S.
charging in a high concentration colloidal suspension
take place. The composite is baked onto metal
substrate at 500°C in H 2 .
20
20070148335(06/28/2007)
Electrode is processed by spreading a paste containing
Tanaka, Hideki; Katai,
activated carbon, polytetrafluoroethylene (binder),
Kazuo/Tdk
and carbon black (conducting agent) mixed in a
Corporation, Japan
solvent (n-methyl-2-pyrolidone) onto a current
collector such as aluminum, then solvent is evaporated
and material compressed into an electrode.
