摘要： 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.

摘要： A battery includes a battery element, housing body, and valve device. The housing body has a laminate including a base material, barrier, and heat-sealable resin layers. The valve device is in communication with the housing body inside. A joined edge portion in which the mutually facing heat-sealable resin layers are fused together is formed in a housing body peripheral edge portion. The valve device includes first and second portions. A valve mechanism reduces the housing body internal pressure if it is increased due to gas generated in the housing body is formed in the first portion. An air passage guides gas generated in the housing body toward the valve mechanism is formed in the second portion. The first portion is located on a joined edge portion edge outer side. At least a portion of the second portion is sandwiched between the heat-sealable resin layers in the joined edge portion.

摘要： A battery includes a battery element, a housing body, and a valve device. The housing body houses the battery element. The valve device is in communication with the inside of the housing body. Heat-sealable resin layers face each other in a peripheral edge portion of the housing body. A joined edge portion in which the mutually facing heat-sealable resin layers are fused together is formed in the peripheral edge portion of the housing body. The valve device is configured to reduce an internal pressure of the housing body if the internal pressure is increased due to gas generated in the housing body. The valve device includes a first portion that is located on an outer side of an edge of the joined edge portion and a second portion that is sandwiched between the heat-sealable resin layers in the joined edge portion.
