Abstract
A battery pressing device for pressing a battery cell, the battery cell including an external casing, an electrolyte, a battery element in which electrodes and a separator are arranged in layers in the external casing, electrode terminals extending out of the external casing from an end of the battery element, and an insulating member for preventing short-circuiting of the electrode terminals attached to the electrode terminals inside the external casing, the battery pressing device includes a pressing member configured to press the battery cell in a layering direction of the battery element over a region so as to avoid pressing the insulating member inside the external casing.
