Help narrow US patent applications before they become patents HERE
QUESTION - Have you seen anything that was published before August, 2010 that discusses:
A capacitor with a 3 dimensional electrode made of sintered material
If so, please submit evidence of prior art as an answer to this question. Only one piece of prior art per answer below. We welcome multiple answers from the same individual.
TITLE: Sintered Capacitor Electrode Including a 3-Dimensional Framework
Summary: This patent relates generally to sintered electrodes including a 3-Dimensional (“3D”) framework with specific applications to batteries in medical devices.
Publication Number: US20130041420 A1
Assignee: Gregory Sherwood
Prior Art Date: Seeking prior Art predating August, 2010
Open for Challenge at USPTO: Open through October 1, 2013
Note: This application has an August, 2011 priority date, so prior art should preferably predate August, 2010 but art prior to June, 2011 can also be used.
Claim 1 requires each and every element below:
An apparatus, comprising:
a capacitor case sealed to retain electrolyte;
at least one electrode disposed in the capacitor case, the at least one electrode comprising a sintered portion disposed on a current collector formed of a framework defining cells extending to three axes;
a conductor coupled to the current collector in electrical communication with the sintered portion, the conductor sealingly extending through the capacitor case to a terminal disposed on an exterior of the capacitor case with the terminal in electrical communication with the sintered portion;
a second electrode disposed in the capacitor case;
a separator disposed between the electrode and the second electrode; and
a second terminal disposed on the exterior of the capacitor case and in electrical communication with the second electrode, wherein the terminal and the second terminal electrically are isolated from one another.
In English this means:
A sealed capacitor with electrolyte inside a case
A 3D electrode made of sintered material as part of the capacitor
A wire or other conductor that connects the inside of the capacitor to a terminal on the ouside of the case
Another (2nd) electrode inside the case
That second electrode isolated from the first one
Another terminal on the outside of the case, electrically coupled to the second electrode, but isolated from the first terminal
Good prior art would be evidence of a device that had each and every one of these elements prior to August, 2010.
