Abstract
Official abstract text for this publication.
A sealed storage battery that is easy to produce, has a low short circuit risk, and has an improved total energy density is provided. A battery includes a first metal sheet having a recessed portion, the recessed portion having a flange portion at its periphery, a multilayer electrode assembly housed in the recessed portion, and a second metal sheet covering the flange portion and the recessed portion. The first metal sheet and the second metal sheet also serve as electrodes. The flange portion is joined to the second metal sheet with a hot-melt resin. A joint between the flange portion and the second metal sheet is folded back toward the recessed portion. An outer edge of the flange portion folded back toward the recessed portion protrudes relative to an outer edge of the second metal sheet folded back toward the recessed portion.
