WO 2011078901
Composite synthesized from MnO 2 and TiO 2 in
(06/30/2011)
preferable weight ratio of 95:5 is provided. Testing of
Raghurama, Raju/
material yields preferred wt% values of electrodes as
Honeywell International
75, 20, and 5% for TiO2–MnO2 composite, polymer
Inc.
binder, and carbon black, respectively.

20110051316 (03/03/2011)
Functionalized graphene sheets are coated with
Jun, Liu; Aksay, Iihan A.;
mesoporous metal oxides. A mesoporous silica layer
Kou, Rong; Wang,
was coated using this nanocomposite as electrode
Donghai/Battelle
material. A 171 F/g double-layer capacitance was
Memorial Institute,
exhibited by the graphene sheets alone at scan rate of
Princeton University, U.S.
2mV/s.

20100233496 (09/16/2010)
Metal oxide developed from Cu, Ag, Au, Ni, Cr, Sn, Cd,
Kim, Hak-Kwan; Ra,
Pb, Rd, Pt, In, Ru, Mn, Zn, and Co achieved via
Seung-Hyun; Bae,
immersion technique. Suggested transition metal
Jun-Hee; Jung, Hyunoxides for electrode use are MnO 2 , RuO 2 , CoO, and
Chul/Samsung ElectroNiO.

20100238607 (09/23/2010)
Metal nanostructures formed for electrode design on
Park, Jin-hwan; Park,
conductive substrate pointing perpendicular to
Sung-ho; Shin, Tae-yeon/
substrate. Metals used include at least one from a
Samsung Electronics Co.,
group consisting of Au, Ag, Ni, Cu, Pt, Ru, Mn and Li.
Ltd., South Korea
Metal oxides shown to integrate are chosen from a
group consisting of RuO 2 , MnO 2 , IrO 2 , NiO x (0 < x <2),
and CoO x (0 < x <2). A porous polymer (Nafion,
Aciplex, Flemion or Dow) may be coated on metal
oxide layer to bind layer to nanometal structure.

(WO 2010120560)
Composite electrode material of Mn and Fe metal
(10/21/2010)
oxides with ratio ranging from 3.5:1 to 4.5:1 for use in
Risser, Stephen M.;
ESs. Metal oxides react to form gel and are
Mcginniss, Vincent; Tan,
subsequently dried in supercritical CO 2 to form
Bing; Spahr, Kevin;
powder. An electrode with a weight composition of 15
Castenada-Lopez,
to 60% carbon and 40 to 80% metal oxide nanoparticles
Homero/Battelle
achieved minimum specific capacitance of 500 F/g at
Memorial Institute, U.S.
1 mV/s in 1M KOH electrolyte.

WO 2010028162
Multilayer electrodes use an array of metals and metal
(03/11/2010)
oxides [Zn, Co, Ni, Li, TiO 2 , RuO 2 , Fe 3 O 4 , WO 3 ,
Gruner, George/University
V 2 O 5 ,Ni(OOH)], carbon and carbon derivatives
of California, U.S.
(graphite, carbon black, carbon nanotubes, activated
carbons, and aerogels) and conducting polymers
(polyaniline, polythiophene, polypyrrol, and PEDOT).
Specific use of carbon networks and polyaniline
coating was found to increase capacitance
significantly; this configuration showed capacitance of
0.016 F/m 2 .
