This invention makes it a subject to shorten the doping time of lithium ion with respect to an electrical storage device. n The electrode stacking unit 12 of the electrical storage device 10 is constituted by a positive electrode 14 and a negative electrode 15 which are alternately stacked, and a lithium electrode 16 is disposed on the outermost side of the electrode stacking unit 12 with a negative electrode 15. Are arranged opposite to). The charge / discharge unit 21 provided with the 1st and 2nd electricity supply control parts 21a and 21b is connected to the positive electrode terminal 18, the negative electrode terminal 19, and the lithium electrode terminal 20. As shown in FIG. Electrons are moved from the lithium electrode 16 to the positive electrode 14 through the first conduction control unit 21a, and lithium ions are doped from the lithium electrode 16 to the positive electrode 14. In addition, electrons are moved from the lithium electrode 16 to the negative electrode 15 through the second conduction control unit 21b, and lithium ions are doped from the lithium electrode 16 to the negative electrode 15. Thus, by doping lithium ion to both the positive electrode 14 and the negative electrode 15, it becomes possible to significantly shorten a doping time. n n Electrical storage devices, lithium ion, doping, positive electrode |
