    摘要： It is an object to provide a cathode for a secondary lithium battery in which adhesiveness and flexibility thereof are simultaneously achieved and the thickness thereof is made large, and the secondary lithium ion battery that has a large capacity and is excellent in safety and cycle life using the cathode.The cathode includes a current collector and a cathode mixture layer formed on the surface of the current collector. The cathode mixture layer is formed by stacking two layers one on another, each of which contains a cathode active material, a conductive material and a binder, and the cathode active material contains a lithium-containing composite oxide that forms a polyanion. Of the two layers, the binder that composes a first layer that is in contact with the current collector contains a polymer formed by polymerizing at least one of monomers consisting of a monomer derived from 1-olefin and a monomer derived from a vinyl compound; and the binder that forms a second layer formed on the first layer contains a fluorine resin.

    摘要： The present invention provides superconductors capable of being used at temperatures to which the superconductor can be cooled in liquid nitrogen and of carrying current in a high critical current density in a magnetic field, and superconducting apparatuses employing the superconductors and more advantageous in costs than the conventional superconducting apparatuses. A superconducting wire is formed by combining a metallic body of a cubic aggregate structure and an oxide superconducting substance. The present invention provides superconductors, superconducting wires, superconducting magnets and applied superconducting apparatuses having a high superconducting critical current density. The applied super conducting apparatuses employing the superconductors or the superconducting wires in accordance with the present invention are able to operate when cooled in liquid nitrogen-and can be manufactured at costs lower than those of the conventional superconducting apparatuses.
