Abstract: An object of the present disclosure is to make it possible to efficiently release moisture, gas, and the like from the inside of an exterior body when moisture enters inside an exterior body for some reason and gas and the like is generated after a battery cell is contained inside the exterior body, while inhibiting an inrush of moisture to the inside of the exterior body after the battery cell is housed inside the exterior body. Provided is a battery structure comprising an exterior body and at least one battery cell housed inside of the exterior body, wherein the exterior body comprises an openable and closable inlet introducing dry air to the inside of the exterior body from the outside of the exterior body, and an openable and closable outlet separate from the inlet releasing gas from the inside of the exterior body to the outside of exterior body, and wherein both of the inlet and the outlet are closed, pressure inside the exterior body is kept higher than atmospheric pressure.

Abstract: The present specification discloses a technology for protecting a portion where corrosion may occur in the assembled battery. An assembled battery includes a plurality of battery packs. Each of the battery packs includes a housing with an opening at a top thereof, a cover plate, and a relief valve. The cover plate is welded at the opening which seals the housing. The relief valve is provided on the cover plate. The assembled battery hardier includes an exhaust cover and an insulating sheet. The exhaust cover covers the relief valve of each of the battery packs, and guides, toward the outside of the assembled battery, an internal gas that comes out of the relief valves. The insulating sheet may cover a portion of a welded line between the housing and the cover plate of each battery pack, and the portion faces the exhaust cover.
