Publication number: 20150325828Abstract: The present invention relates generally to electrochemical energy storage devices such as Li-ion batteries, and more particularly to a method of providing uniform ceramic coatings with controlled thicknesses for separators in such storage devices. Some embodiments of the invention utilize a layer by layer coating of nano/micro-sized particles dispersed in a solvent, which can be aqueous or non-aqueous. Other embodiments of the invention utilize a dry process such as PVD for depositing a ceramic film on a porous polyolefin separator. According to certain aspects of the invention, advantages of this approach include the ability to achieve a denser more uniform film with better controlled thickness with less waste and higher yield than current ceramic coating technology. An advantage of a ceramic coated separator is increased safety of cells.Type: ApplicationFiled: December 11, 2013Publication date: November 12, 2015Inventors: Subramanya P. HERLE, Joseph G. GORDON

Thin film structures and devices with integrated light and heat blocking layers for laser patterning
Patent number: 8993443Abstract: Selective removal of specified layers of thin film structures and devices, such as solar cells, electrochromics, and thin film batteries, by laser direct patterning is achieved by including heat and light blocking layers in the device/structure stack immediately adjacent to the specified layers which are to be removed by laser ablation. The light blocking layer is a layer of metal that absorbs or reflects a portion of the laser energy penetrating through the dielectric/semiconductor layers and the heat blocking layer is a conductive layer with thermal diffusivity low enough to reduce heat flow into underlying metal layer(s), such that the temperature of the underlying metal layer(s) does not reach the melting temperature, Tm, or in some embodiments does not reach (Tm)/3, of the underlying metal layer(s) during laser direct patterning.Type: GrantFiled: August 8, 2012Date of Patent: March 31, 2015Assignee: Applied Materials, Inc.Inventors: Daoying Song, Chong Jiang, Byung-Sung Leo Kwak, Joseph G.

Patent number: 4165155Abstract: An optical modulator suitable for use with a collimated light beam having a moderate cross section and a fast response time and operational at relatively low voltage includes, for example, a glass prism and a smooth metal surface that are separated by an adjustable gap. The gap is filled with a medium, for example, air, having an index of refraction lower than the prism. A beam of monochromatic light is passed into the prism at a specific angle of incidence to undergo total internal reflection at the glass prism-gap interface. A change of approximately 1 micron in the thickness of the gap is sufficient to change the reflectivity from greater than 95% to essentially zero. The size of the gap is mechanically adjusted and this mechanical device determines the frequency response of the light modulation.Type: GrantFiled: March 27, 1978Date of Patent: August 21, 1979Assignee: International Business Machines CorporationInventors: Joseph G.
