<p>PROBLEM TO BE SOLVED: To provide a power storage device capable of suppressing a fracture part of a current cutoff device from being damaged due to opening or closing of a lid part of a case during assembly manufacturing.SOLUTION: A power storage device 100 according to an embodiment comprises: an electrode assembly 60 laminated with a plurality of sheet-like negative and positive electrodes each of which includes collector parts 67 and 65; a case 1 with a body part 62 housing the electrode assembly 60 and a lid part 63; a positive electrode terminal 119 and a negative electrode terminal 19 provided in the lid part 63; and a current cutoff device 2 including an energizing path and provided between the collector part 67 of the negative electrode and the negative electrode terminal 19. The collector part 67 of the negative electrode and the collector part 65 of the positive electrode are aggregated to one end in a lamination direction of the electrode assembly 60. The collector part 67 of the negative electrode is electrically connected to the negative electrode terminal 19, and the collector part 65 of the positive electrode is electrically connected to the positive electrode terminal 119. The current cutoff device 2 is bonded to the electrode assembly 60 via a buffer member 30 having an adhesive surface.</p> |
