    Abstract: PROBLEM TO BE SOLVED: To provide a collector for a nonaqueous electrolyte battery and for a power storage component such as an electric double layer capacitor, in which high-rate characteristics can be enhanced by reducing the internal resistance.SOLUTION: In a collector 1 where a conductive acrylic resin layer 5 is formed on at least one surface of a conductive base material 3, the acrylic resin layer 5 contains an acrylic resin and conductive particles, and the water contact angle on the surface of the acrylic resin layer measured by the θ/2 method in a constant temperature chamber of 23°C is 30-110 degrees. An electrode structure 7 is also obtained by forming an active material layer 9 in the collector 1.

    Abstract: PROBLEM TO BE SOLVED: To provide aluminum alloy foil for a lithium secondary battery, which is used for the positive electrode material of the lithium ion secondary battery, in which cutting and peeling of an active material are not caused since failure such as deformation and fracture are hardly caused when the active material is applied, and also, upon its storage into a case as a wound body, which has satisfactory storage property into the case, since its repulsion force is small. SOLUTION: The aluminum alloy foil for the lithium ion secondary battery has a composition composed of, by mass, 0.01 to 0.60% Si, 0.2 to 1.0% Fe, 0.05 to 0.50% Cu and 0.5 to 1.5% Mn, and the balance Al with inevitable impurities. The aluminum alloy foil is characterized in that tensile strength is ≥240 MPa, proof stress after heat treatment at 100°C for 30 min is ≤270 MPa, and the tensile strength after heat treatment at 180°C for 30 min is ≥200 MPa. There is also provided a method for producing the aluminum alloy foil for the lithium ion secondary battery. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a collector allowing active material layers to be correctly stacked on and integrated with both its front and back surfaces, and of preventing the active material from falling off in manufacturing a secondary battery or in using it. SOLUTION: In this collector A, front and back conductive resin layers 2 and 3 are stacked on and integrated with both front and back surfaces of metal foil 1; multiple through-holes A1 penetrating to the back surface of the metal foil 1 from the front surface of the resin layer 2 are formed; the active material layers can be stacked and integrated in separate processes on the one-side surface basis because the back-side openings of the through-holes A1 are closed by the resin layer 3; and thereby, the active material layers can simply and surely be stacked on and integrated with both the front and back surfaces of the collector by using a simple facility while correctly adjusting the thicknesses of the active material layers.
