<P>PROBLEM TO BE SOLVED: To provide an electrode plate for alkali metal ion secondary batteries which excels in cycle characteristics against repeated charging/discharging, as well as an alkali metal ion secondary battery and a battery pack using the electrode plate. <P>SOLUTION: An alkali metal ion secondary battery electrode plate 1 comprises a current collector 2, an anchor layer 3 disposed directly or indirectly on the current collector, and an electrode active material layer 6 disposed directly or indirectly on the anchor layer. The anchor layer contains metal oxides, and is formed with the metal oxides joining to each other. The electrode active material layer 6 contains active material particles 4 and binding components 5, the active material particles being stuck to each other by the binding components. These members are composed in such a way that the anchor layer is laminated with the metal oxides as they stick fast to a base face on the current collector, the face on which they abut directly, and that the electrode active material layer is laminated with the binding components as they stick fast to a base face on the anchor layer, the face on which they abut directly. <P>COPYRIGHT: (C)2013,JPO&INPIT |
