Energy storage device

Abstract

A power storage device according to the present invention comprises a plurality of first power-storage elements. Each of the plurality of first power-storage elements comprises a container that is flat in a first direction, and electrode terminals disposed in a second direction intersecting the first direction of the container. The container comprises a first surface facing the first direction, a second surface facing the second direction and on which the electrode terminals are not disposed, and a gas discharge valve provided on the first surface and / or the second surface. The plurality of first power-storage elements are disposed side-by-side in a third direction intersecting the first and second directions.
