20140099544 | ELECTRODE MATERIAL AND MANUFACTURING METHOD THEREOF - Provided is an electrode material with excellent tab weldability and realizing decreased contact resistance with an active material layer. A collector (electrode material) ( | 04-10-2014 |
20150136608 | ALUMINUM ALLOY HAVING EXCELLENT ANODIC OXIDATION TREATABILITY, AND ANODIC-OXIDATION-TREATED ALUMINUM ALLOY MEMBER - An aluminum alloy comprising more than 3.5% and up to 6.0% of Mg, 0.02 to 1.0% inclusive of Cu, 0.02 to 0.1% inclusive of Cr, and a remainder made up by Al and unavoidable impurities, wherein the contents of Si and Fe in the unavoidable impurities are limited to 0.05% or less and 0.05% or less, respectively, and wherein the number of intermetallic compound particles contained in the aluminum alloy and having a maximum length of 4 μm or more is 50 particles or less per 1 mm | 05-21-2015 |
20150211141 | ANODIZED ALUMINUM FILM - Provided is an anodized aluminum film formed on a surface of a substrate that comprises aluminum or an aluminum alloy, the anodized aluminum film having a structure constituted of a single anodized film layer or a structure composed of superposed anodized film layers of two or more different kinds, wherein the outermost anodized film has a degree of film formation, defined by equation (1), of 1.3 or more and the proportion of the thickness of this anodized film in the entire film thickness is 3% or higher. Thus, the anodized aluminum film is inhibited from cracking in bent portions. As a result, the substrate is inhibited from corroding in corrosive-gas atmospheres, and a decrease in withstand voltage characteristics due to film cracking is inhibited. With this anodized aluminum film, enhanced withstand voltage characteristics can hence be attained. | 07-30-2015 |

20150325863 | MATERIAL FOR FUEL CELL SEPARATORS AND METHOD FOR PRODUCING SAME - A material for fuel cell separators having excellent adhesion between a base and a carbon layer, excellent conduction durability and excellent production efficiency; and a method for producing the material are provided. The method includes: a coating step wherein a coating layer that contains carbon and a binder compound containing a carbon atom and an oxygen atom is formed on the surface of a titanium base of titanium or a titanium alloy with a thickness of 40-200 μm; and a heat treatment step treating the titanium base covered with the coating layer. The titanium base covered with the coating layer is wound into a coil shape and then subjected to the heat treatment carried out in a vacuum atmosphere of 10 Pa or less. A carbon layer and an intermediate layer containing titanium carbide are formed from the coating layer in the heat treatment step. | 11-12-2015 |
