PROBLEM TO BE SOLVED: To provide a flexible power storage device, or a power storage device of which the capacity and cycle characteristics do not easily deteriorate even when the power storage device is curved.SOLUTION: A power storage device includes electrodes 111 and 115 that include collectors 101 and 105, active material layers 102 and 106, a friction layer 103 and a separator 108, respectively, in which the active material layers 102 and 106, the current collectors 101 and 105, and the friction layer 103 are stacked in the order, respectively, more specifically, the active material layers 102 and 105 are arranged on one surface of the collectors 101 and 106, respectively, while the friction layer 103 is arranged on the other surface. In addition, a power storage device includes the electrode as at least one of a positive electrode 111 and a negative electrode 115.SELECTED DRAWING: Figure 3 |
