Document Type and Number:
Japanese Patent JP6851131
Kind Code:
B2
Abstract:
A secondary battery with an exterior body having a novel scaling structure, and a structure of a sealing portion that relaxes a stress of deformation are provided. The secondary battery includes a positive electrode, a negative electrode, an electrolyte solution, and an exterior body enclosing at least part of the positive electrode, at least part of the negative electrode, and the electrolyte solution. The exterior body includes a first region having a shape with a curve, a shape with a wavy line, a shape with an arc, or a shape with a plurality of inflection points, and a second region having the same shape as the first region.
