PROBLEM TO BE SOLVED: To provide an electrode structure for a positive electrode, which enables the suppression of gas generation without worsening the capacitance and load characteristic of a nonaqueous electrolyte power storage device.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 current collector and including a positive electrode active material containing graphite allowing anions to go thereinto and out thereof, and a conductive assistant. In the electrode, the following relation holds as to the quantity of the conductive assistant per unit area in a thickness direction of the positive electrode material layer: 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. In the nonaqueous electrolyte power storage device, the electrode of (1) is used as the positive electrode.SELECTED DRAWING: None |
