1
WO 2010028162
ESs of both double-layer and battery-like materials
(03/11/2010)
such as porous carbon and RuO 2 , respectively, form
Gruner, George/University
multilayer electrode structures. The two electrodes
of California, U.S.
either combine the two materials or use them
separately. Device configuration consists of basic
electrode, separator with electrolyte, and electrode
design.

20090320253 (12/31/2009)
Planar electrodes are arranged in series and conductive
Bourcier; Roy Joseph/
carbon material is applied to an electrode when it is
Corning Incorporated, U.S.
between at least two alternating electrodes to provide
efficient electrical contact between them. Stacks of
discrete sheet electrodes have electrically insulating
material disposed between electrodes. Electrodes can
be of any shape or size and have first face, opposing
second face, and defined thickness from first face to
second.
3
20090316336 (12/24/2009)
Bipolar membrane separator with first side having
Fan, Qinbai/Gas
plurality of anions to face positive electrode and
Technology Institute
second side having plurality of cathodes facing
negative electrode. Membrane builds its own electrical
field to become a sub-capacitor with respect to
external electric field to prevent recombination
through maintained charge separation.
4
20100302708 (10/30/2008)
Two end electrodes connect to power source, with at
Shiue, Lih-Ren; Goto,
least one electrode having no connection at all. If the
Masami/Linxross,
number of intervening electrodes exceeds one,
Inc., Japan
separators must be placed so intervening electrodes
are not in contact with each other. Intervening
electrodes are wound concentrically on cylindrical
element. A cylindrical 10 V sample measured at a 1 A
discharge rate showed capacitance of 1.56 F, IR drop
of 0.38 mm, and measured ESR of 192 mΩ at 1 KHz.
5
20080013255 (01/17/2008)
Two-sided electrode film element with single top side
Schneuwly, Adrian/
punched to create several cavities. Electrode foil
Maxwell Technologies Inc.,
element is then affixed onto bottom side. Second
U.S.
electrode film undergoes same process and is affixed
to other side of foil element.
6
20070139865 (06/21/2007)
Structure for electrochemical device that enables easy
Sakamoto, Ryuichi;
passage of electrolyte solution into interior of member
Takeishi, Minoru;
of stack or bank. Expansion of polarized electrode
Koshimizu, Masahiro/
layers is effectively suppressed via a pair of fixed
TDK Corporation, Japan
collecting plates. Each plate has a depressed portion to
exert pressure on other stacked members, while the
protruding portion forms a gap to permit electrolyte
passage.
