20070139865 (06/21/2007)
Porous active carbon particles derived from various
Sakamoto, Ryuichi;
precursors and polytetrafluoroethylene are used as
Takeishi, Minoru;
electrode material and binder material, respectively.
Koshimizu, Masahiro/
Fluoro rubbers such as vinylidene fluoride,
TDK Corporation, Japan
hexafluoropropylene, and tetrafluoropropylene can be
used as binder. Specific surface area of porous
particles is preferably between 2000 and 2500 m 2 /g to
obtain high volume capacity.

20070134151 (06/14/2007)
Halogenated polymers such as poly(vinylidene fluoride
Jo, Seong-Mu; Kim,
and poly(vinylidenefluoride-co-hexafluoropropylene)
Dong-Young; Chin,
with preferred diameter of 1 to 1000 nm are mixed
Byung-Doo; Hong,
with graphitizing metal nanograin catalyst (Pt, Ru, Cu,
Sung-Eun/Korea Institute
Fe, Ni, Co, Pd, W, Ir, Rh, Sr, Ce, Pr, Nd, Sm, Re, B, Al),
of Science and
catalyst precursor (metal chlorides: CuCl 2 , COCl 2 ,
Technology, South Korea
OsCl 3 , CrCl 2 ,FeCl 3 ), metal nitrides: Fe(NO 3 ) 3 and
Pd(NO 3 ) 2 ) or organic metal compounds such as iron
acetylacetonate. Chosen mixture is electrospun at
charge of 9 kV, and resulting fiber treated and heated
at carbonizing temperature between 800 and 1800°C in
N 2 . The resulting excellent ultrafine carbon fiber can
then be processed as electrode material.

20060250750 (11/06/2006)
Polyimide silicone from polyamic acid precursor is mixed
Yoshinori Yonedu;
with conductive material, preferably carbon or transition
Michihiro Sugou;
metal oxide to create a minimal resistance active
Yoshinori Ogawa/
electrode. Mass ratio of conductive material to polyimide
Shin-Etsu Chemical Co.
silicone is preferably 99:1 to 80:20.
26
20060098389 (05/11/2006)
Single wall carbon nanotubes mixed with copolymer
Liu, Tao; Kumar, Satish/
such as acrylonitrile or methylacrylate are made into a
Georgia Tech Research
suspension and cast on glass plate for film
Corporation
development. Subsequent activation of films by CO 2
and Ar at 700°C for 8 min. tested at current density of
01 mA to yield 167 F/g.
