|20150255793||CARBON MATERIAL FOR NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERY, MANUFACTURING PROCESS THEREFOR AND USE THEREOF - A carbon material for negative electrodes in lithium ion secondary battery, wherein a specific surface area is not less than 1.5 m||09-10-2015|
|20150255788||NEGATIVE ELECTRODE FOR SECONDARY BATTERY AND SECONDARY BATTERY - An object of the present invention is to provide a secondary battery capable of rapid charging and discharging at a high current, in which, even when a titanium-containing oxide is used as a negative electrode active material, the internal resistance and impedance of the secondary battery are low without adding a material, which does not contribute to electrical capacity, such as a conductive assistant to a negative electrode active material layer in a large amount. Provided is a negative electrode for a secondary battery including: metal foil; and a negative electrode active material layer that is formed on a single surface or both surfaces of the metal foil and includes a titanium-containing oxide as a negative electrode active material, in which a film containing a conductive material is formed between the metal foil and the negative electrode active material layer.||09-10-2015|
|20150255680||LIGHT-EMITTING DIODE, LIGHT-EMITTING DIODE LAMP, AND ILLUMINATION DEVICE - In a light-emitting diode, a plurality of dot-shaped ohmic contact electrodes are provided between a metal reflective film and a compound semiconductor layer, an ohmic electrode and a surface electrode composed of a pad portion and a plurality of linear portions connected to the pad portion are provided in that order on the opposite side of the compound semiconductor layer from the semiconductor substrate, the surface of the ohmic electrode is covered with the linear portions, the ohmic contact electrodes and the ohmic electrode are formed in positions that do not overlap with the pad portion in plane view, and among the plurality of ohmic contact electrodes, 5% or more and 40% or less of the ohmic contact electrodes are disposed in positions that overlap with the linear portions in plane view.||09-10-2015|
