LITHIUM ION CAPACITOR, POWER STORAGE DEVICE, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a power storage device that has a high reliability and a preferred structure for delivering a higher output.

SOLUTION: A container 12 of a lithium ion capacitor 10 contains an electrode structure 11 that is formed by winding positive electrodes, separators and negative electrodes in a stacking state. The container 12 includes three terminal members: a cylindrical side terminal member 50 that has openings 50a and 50b at both ends; and a first cover terminal member 51 and a second cover terminal member 52 that cover the openings 50a and 50b. The terminal members 50 to 52 are fixed by being caulked via an insulator 54. In the container 12, a lithium metal 60 for pre-doping is connected to the side terminal member 50, a positive electrode is connected to the first cover terminal member 51, and a negative electrode is connected to the second cover terminal member 52.
