<P>PROBLEM TO BE SOLVED: To provide an electrode which has superior rate characteristics and cycle characteristics. <P>SOLUTION: The electrode includes a current collector and an electrode layer which is formed on the current collector and contains an electrode active material and a conducting material. In the electrode layer, the concentration of the conducting material on an electrode layer surface closer to the current collector is lower than that of the conducting material on an electrode layer surface opposite the surface closer to the current collector. <P>COPYRIGHT: (C)2009,JPO&INPIT |
