摘要： An electrode material for a secondary battery includes crystal primary particles of an electrode active material which releases or absorbs cations of a monovalent or divalent metal when subjected to electrochemical oxidation or reduction and which has a crystal lattice in which the cations can move only in a one-dimensional movable direction during the process of oxidation or reduction. The electrode material also includes an ion-conductive substance and conductive carbon which coexist on the surface of the primary particles, in which the ion-conductive substance has a property which allows two or three-dimensional movement of the cations, and the cations are movable via a layer in which the ion-conductive substance and the conductive carbon coexist.

摘要： This invention reduces planar defects which occur within a silicon carbide single crystal when a silicon carbide single crystal is epitaxially grown on a single crystal substrate.The process for producing a silicon carbide single crystal in which a silicon carbide single crystal layer is epitaxially grown on the surface of a single crystal substrate is a process in which a plurality of undulations that extend in a single, substantially parallel direction on the substrate surface is formed on the single crystal substrate surface; undulation ridges on the single crystal substrate undulate in the thickness direction of the single crystal substrate; and the undulations are disposed so that planar defects composed of anti-phase boundaries and/or twin bands that propagate together with the epitaxial growth of the silicon carbide single crystal merge with each other.
