Publication number: 20090311418Abstract: Electrical separators for batteries, especially lithium batteries, having a shutdown mechanism. A process for their production. An electrical separator is used in batteries and other systems in which electrodes have to be separated from each other while maintaining ion conductivity. Safety is very important in lithium batteries, since in contrast to other types of battery (Pb, NiCd, NiMeH) the solvent for the electrolyte is not water but a combustible solvent.

This is achieved by an electrical separator having a shutdown layer which comprises particles which melt at a desired temperature, close the pores of the separator, and so stop ion flow. Since the separator also comprises a porous inorganic (ceramic) layer on a carrier, the cells cannot melt down as a result of a completely melted separator.Type: ApplicationFiled: August 24, 2009Publication date: December 17, 2009Applicant: EVONIK DEGUSSA GmbHInventors: Volker HENNIGE, Christian HYING, Gerhard HÖRPEL

An atomizer (12) renders a supply of source material (10) into many discrete particles. A force applicator (14) propels the particles in continuous, parallel streams of discrete particles. A collimator (16) controls the direction of flight of the particles in the stream prior to their deposition on a substrate (18). In an alternative embodiment of the invention, the viscosity of the particles may be controlled to enable complex depositions of non-conformal or three-dimensional surfaces. The invention also includes a wide variety of substrate treatments which may occur before, during or after deposition. In yet another embodiment of the invention, a virtual or cascade impactor may be employed to remove selected particles from the deposition stream.Type: GrantFiled: September 20, 2004Date of Patent: September 18, 2007Assignee: Optomec Design CompanyInventor: Michael J. Renn

Patent number: 7214295Abstract: The present invention discloses a method of manufacturing a thin film resistor with a moisture barrier by depositing a metal film layer on a substrate and depositing a layer of tantalum pentoxide film overlaying the metal film layer. The present invention also includes a thin film resistor having a substrate; a metal film layer attached to the substrate; and a tantalum pentoxide layer overlaying the metal film layer, the tantalum pentoxide layer providing a barrier to moisture, the tantalum pentoxide layer not overlaid by an oxidation process.Type: GrantFiled: April 9, 2001Date of Patent: May 8, 2007Assignee: Vishay Dale Electronics, Inc.Inventor: Stephen C. Vincent

Patent number: 7011890Abstract: A method for depositing a low dielectric constant film is provided. The low dielectric constant film includes alternating sublayers, which include at least one carbon-doped silicon oxide sublayer. The sublayers are deposited by a plasma process than includes pulses of RF power. The alternating sublayers are deposited from two or more compounds that include at least one organosilicon compound. The two or more compounds and processing conditions are selected such that adjacent sublayers have different and improved mechanical properties.Type: GrantFiled: March 3, 2003Date of Patent: March 14, 2006Assignee: Applied Materials Inc.Inventors: Son Van Nguyen, Yi Zheng

Patent number: 6936192Abstract: A resistive paste is made by a mixture of a conductive metal powder which is made by mixing 85 to 94 percent by weight of copper powder, 5 to 10 percent by weight of manganese powder, and 1 to 5 percent by weight of tin powder; a mixture of 3 to 7 percent by weight of glass powder and 3 to 7 percent by weight of copper-oxide powder relative to the entire amount of said conductive metal powder; and 7 to 15 percent by weight of vehicle relative to the entire amount of the conductive metal powder and the mixture. The resistive paste is then sintered, and the resistive composition having the low resistance value and low TCR may be obtained. In addition, a resistor is made by forming the resistive element upon a substrate.Type: GrantFiled: September 17, 2003Date of Patent: August 30, 2005Assignee: Koa Kabushiki KaishaInventor: Kouichi Urano

Patent number: 6835412Abstract: A metallized substrate, such as used to make a resonant circuit tag with inductive and capacitive elements in series, has a thin inorganic or polymeric dielectric layer formed on a metal layer. The inorganic layer may be formed by anodizing a surface of the metal layer. The organic layer may be formed by flexographic printing. In both cases, a via hole is formed through the dielectric layer. A second layer of very thin conductive metal is deposited on the dielectric layer and in the via hole. The substrate is subsequently patterned with an etch resist and then etched to form the inductor coil and the capacitor plates, which are interconnected via the metallized via hole.Type: GrantFiled: May 2, 2002Date of Patent: December 28, 2004Assignee: Micrometal Technologies, Inc.Inventor: Thomas F. Burke
