摘要： A battery includes a battery element, a housing body, and a valve device. The housing body is constituted by at least one laminate and includes an interior space in which the battery element is housed, a first housing portion that covers the interior space from a first side in a thickness direction of the battery, and a second housing portion that covers the interior space from a second side that is opposite to the first side in the thickness direction of the battery. The valve device is attached to the housing body and can make the interior space of the housing body be in communication with an external space. A joined edge portion is formed in the housing body as a result of the first housing portion and the second housing portion being fused along respective peripheral edge portions. The valve device is at least partially sandwiched between the first housing portion and the second housing portion in the joined edge portion. The first housing portion includes a bulge portion that is arranged on an inner side of an inner edge of the joined edge portion and bulges toward the first side with respect to the joined edge portion. An inner end of the valve device is located on an outer side of an outer edge of the bulge portion.

摘要： Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on an axis to define a core and an outer circumference. The first electrode includes an uncoated portion at a long side end thereof and exposed out of the separator along a winding axis direction of the electrode assembly. A part of the uncoated portion is bent in a radial direction of the electrode assembly to form a bending surface region that includes overlapping layers of the uncoated portion, and in a partial region of the bending surface region, the number of stacked layers of the uncoated portion is to or more in the winding axis direction of the electrode assembly.
