<P>PROBLEM TO BE SOLVED: To manufacture an electrode enhancing the charge/discharge cycle characteristics in which an active material is less likely to peel off, and a power storage device. <P>SOLUTION: Since the electrode for a power storage device uses a collector, and an electrode on the collector having an active material layer that has particles containing niobium oxide and a granular active material, the charge/discharge cycle characteristics of the power storage device can be enhanced. Furthermore, when the granular active material and the particles containing niobium oxide come into contact with each other, the granular active material is fixed physically, thus minimizing pulverization of the active material due to expansion or contraction incident to charge/discharge of the power storage device, and peeling off from the collector. <P>COPYRIGHT: (C)2013,JPO&INPIT |
