PROBLEM TO BE SOLVED: To provide an electrode for a positive electrode, which enables the increase in charge and discharge efficiencies without decreasing the capacity of a nonaqueous electrolyte power storage device, and enables the suppression of self discharge.SOLUTION: (1) An electrode for a positive electrode of a nonaqueous electrolyte power storage device comprises: a positive electrode current collector; and a positive electrode material layer formed on the positive electrode current collector, including at least a positive electrode active material consisting of soft carbon which allows anions to go thereinto and out thereof, and a conductive assistant. As to the quantity of the conductive assistant per unit area in a thickness direction of the positive electrode material layer, the following condition holds: Positive electrode current collector interface>Electrolyte interface. (2) A nonaqueous electrolyte power storage device comprises at least, a positive electrode, a negative electrode and a nonaqueous electrolyte; the electrode for a positive electrode as described in (1) is used as the positive electrode.SELECTED DRAWING: None |
