The electrode material is mixed to form a suspension having a mixing index of at least about 0.80 and is then formed into a semi-solid electrode.Type: ApplicationFiled: March 15, 2013Publication date: December 19, 2013Applicant: 24M TECHNOLOGIES, INC.Inventors: Tristan Doherty, Pimpa Limthongkul, Asli Butros, Mihai Duduta, James C.

Publication number: 20130328226Abstract: A compression-molded part has a conductive layer embedded in the part during molding of the part. The conductive layer is generally adjacent an outer surface of the part and is preferably formed from a mesh, a foil, a pulled screen, or multiple layers of conductive elements. The part is preferably optimized for use on the exterior of an aircraft for lightning-strike or EMI protection or for use as an antenna. Methods for forming the panels of the invention include placing the conductive layer against a mold surface of a compression mold, then forming the compression-molded part with the conductive layer embedded in the part.Type: ApplicationFiled: July 19, 2012Publication date: December 12, 2013Applicant: BELL HELICOPTER TEXTRON INC.Inventors: Anthony P.

Publication number: 20130330511Abstract: The disclosure relates to a material having a textured surface and exhibiting absorption of electromagnetic waves with gigahertz frequencies. The textured surface can comprise a plurality of protrusions that can permit absorption of such waves. Morphology of the plurality of protrusions can control the absorption properties, e.g., absorption coefficients or specific frequency of absorbed electromagnetic radiation, of such materials. The material can comprise an electrically conductive thermoplastic composite. At least some of the protrusions can be formed of such composite. The material having the texture surface can exhibit broadband absorption.Type: ApplicationFiled: June 8, 2012Publication date: December 12, 2013Inventors: Fred Sharifi, Gregory J. Parker

Publication number: 20130320582Abstract: Provided are electrode layers for use in rechargeable batteries, such as lithium ion batteries, and related fabrication techniques. These electrode layers have interconnected hollow nanostructures that contain high capacity electrochemically active materials, such as silicon, tin, and germanium. In certain embodiments, a fabrication technique involves forming a nanoscale coating around multiple template structures and at least partially removing and/or shrinking these structures to form hollow cavities. These cavities provide space for the active materials of the nanostructures to swell into during battery cycling. This design helps to reduce the risk of pulverization and to maintain electrical contacts among the nanostructures. It also provides a very high surface area available ionic communication with the electrolyte. The nanostructures have nanoscale shells but may be substantially larger in other dimensions.Type: ApplicationFiled: May 9, 2013Publication date: December 5, 2013Applicant: Amprius, Inc.Inventors: Yi Cui, Song Han, Ghyrn E.

Publication number: 20130320583Abstract: Resinous fibers of nanometer to micrometer width dimensions are drawn from a multi-component system by a melt extrusion process. The process includes a step of combining a fiber resin with a water-soluble carrier resin to form a resinous mixture. The resinous mixture is extruded to form an extruded resinous mixture, the extruded resinous mixture having strands of the fiber resin with the carrier resin. The extruded resinous mixture is then contacted with water to separate the strands of the fiber resin from the carrier resin. An electrically conductive fibrous sheet is then formed from the strands of fiber resin. The fibrous sheets are useful as diffusion layers in fuel cells.Type: ApplicationFiled: May 30, 2012Publication date: December 5, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: James Mitchell, Timothy J.
