    Abstract: With a manufacturing method of a graphite sheet, a cavity-forming sheet having a mesh structure or a nonwoven fabric structure is firstly impregnated with polyamide acid and then molded into a sheet. The molded sheet is then heat treated to imidize polyamide acid so as to produce a polyimide sheet composed of polyimide and the cavity-forming sheet disposed in polyimide. The polyimide sheet is then fired in a non-oxidizing atmosphere to pyrolyze the polyimide so as to produce the graphite sheet. The cavity-forming sheet is made of material which maintains a shape thereof when the polyimide sheet is produced and which gasifies and loses at least 80% of its weight when the polyimide is pyrolyzed.

  • Patent number: 9452934
    Abstract: Ultra-large graphene oxide (UL-GO) sheets are formed using a Langmuir-Blodgett (LB) thin film process. Sulfuric acid and nitric acid are applied to interlayers of natural graphite flake to form graphite intercalation compound (GIC) powders. The GIC powders are expanded at a high temperature, and intercalating agents are used to further oxidize the expanded GIC powders by to exfoliating the EG into monolayer graphene oxide (GO) sheets. The GO is sequentially centrifuged and UL-GO sheets are collected. An LB thin film is prepared from the collected sheets and the thin films are reduced and chemically doped.

  • Patent number: 9440375
    Abstract: A hard mask film 2 provided on substrate 1 is formed by tin-containing chromium-containing material. In the chromium-containing material including tin, which forms the hard mask film 2, the etching resistance to fluorine-containing dry etching is equal to or higher than the etching resistance of the tin-free chromium-containing material, and it shows a significantly high etching rate as compared with a chromium-containing material free of tin under conditions for chlorine-containing dry etching. As a result, the time for chlorine-containing dry etching is shortened, and damage to a resist pattern is reduced. Thus, high-precision pattern transfer can be performed. The present invention provides a novel technique for increasing etching process-ability by increasing a dry-etching rate of a hard mask film made of a chromium-containing material while assuring a hard mask function of the hard mask film.

  • Patent number: 9444125
    Abstract: A battery pack is provided that is configured to minimize the risk of battery shorts during a thermal runaway event. The battery pack uses a layer of a thermally conductive, electrically non-conducting epoxy to transfer heat from each of the pack's batteries to an underlying heat sink/heat spreader. A plurality of electrically non-conductive granules, for example fabricated from alumina or silica, is dispersed throughout at least a region of the epoxy layer. As a result of the granules, even if the epoxy layer softens sufficiently during a thermal runaway event to allow movement of the batteries, the granules will prevent the batteries from contacting the underlying heat sink/heat spreaders and shorting out, one benefit of which is decreasing the likelihood of an initial thermal runaway event propagating throughout the entire battery pack.
