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.
