  • Publication number: 20220077538
    Abstract: A valve device and an assembled battery according to which even if the valve device operates, deterioration of an outer layer of a storage body is unlikely to be accelerated. The valve device is attached to a first storage body that stores a battery. The valve device includes an attachment part, a valve device main body, and a gas passage part. The attachment part is attached to the first storage body. The valve device main body reduces pressure inside the first storage body in a case where the pressure increases due to gas produced inside the first storage body. The gas passage part is between the attachment part and the valve device main body, and allows gas that passes through the attachment part to pass through the valve device main body. The valve device main body is located outward of an outer periphery of the first storage body.
