Publication number: 20110183203Abstract: Methods and devices arising from the practice thereof for making and using battery electrodes formed onto ion permeable, electrically non-conductive substrates, preferably battery separators are disclosed herein. Electrodes are formed onto substrates using a variety of methods including, but not limited to, spray coating and electrophoretic deposition. Electrically conductive layers may be applied to the electrode coating layer side opposite or adjacent to the substrate to act as current collectors for the battery. Multilayer devices having alternating layers of conductive layers, electrode layers and substrates, wherein the conductive layers may be in electrical communication with other conductive layers to form a battery.Type: ApplicationFiled: January 27, 2011Publication date: July 28, 2011Inventors: Chunsheng Du, Clark Dong, Lawrence S.

Publication number: 20110183137Abstract: A method of maintaining an article, e.g. an engine and its components in a potentially explosive environment at a surface temperature above that allowed by safety regulations, e.g. above 200° C. This is achieved by applying a composition comprising: about 9 to about 90% of one or more silicone rubber about 9 to about 90% of one or more fluorosilicone rubber about 0.05 to about 1% of one or more vulcanisation catalyst and about 0 to about 20% of one or more additive to the surface of the article and curing the composition, and maintaining the article in a potentially explosive environment such that the surface temperature of the article is above that allowed by safety regulations but the surface temperature of the coating does not exceed that allowed by safety regulations.Type: ApplicationFiled: August 7, 2009Publication date: July 28, 2011Inventors: Lee Spraggon, Mark Ellis Jackson

Publication number: 20110174633Abstract: An electrolytic cell is provided that can include: a first electrode plate including a first surface that can include a graphite material; a second electrode plate including a second surface that can include a graphite material opposing the first surface; an electrolytic reaction zone between the first surface and the second surface; and an inlet to and an outlet from the electrolytic reaction zone. The first electrode plate and the second electrode plate can include resin-impregnated monolithic graphite plates. The first electrode plate and the second electrode plate can form opposite internal walls of a chamber for the electrolytic reaction and thus can be provided without a container for containing the electrode plates. Methods are also provided for flow-through-resin-impregnating porous, monolithic graphite plates to form electrode plates.Type: ApplicationFiled: March 30, 2011Publication date: July 21, 2011Applicant: ProChemTech International, Inc.Inventor: Timothy Edward KEISTER

Publication number: 20110175038Abstract: Compositions of carbon nanoflakes are coated with a low Z compound, where an effective electron emission of the carbon nanoflakes coated with the low Z compound is improved compared to an effective electron emission of the same carbon nanoflakes that are not coated with the low Z compound or of the low Z compound that is not coated onto the carbon nanoflakes. Compositions of chromium oxide and molybdenum carbide-coated carbon nanoflakes are also described, as well as applications of these compositions. Carbon nanoflakes are formed and a low Z compound coating, such as a chromium oxide or molybdenum carbide coating, is formed on the surfaces of carbon nanoflakes. The coated carbon nanoflakes have excellent field emission properties.Type: ApplicationFiled: January 26, 2009Publication date: July 21, 2011Inventors: Kun Hou, Dennis M. Manos, Ronald A. Outlaw
