Abstract

A battery includes a first portion and a second portion, in which the first portion includes a first positive electrode layer, a first negative electrode layer, and a first solid electrolyte layer located between the first positive electrode layer and the first negative electrode layer, in which the second portion includes a second positive electrode layer, a second negative electrode layer, and a second solid electrolyte layer located between the second positive electrode layer and the second negative electrode layer, in which the first portion and the second portion are in contact with each other, the second portion is more sharply bent than the first portion, the first solid electrolyte layer contains a first binder, the second solid electrolyte layer contains a second binder, and the second solid electrolyte layer containing the second binder has higher flexibility than a flexibility of the first solid electrolyte layer containing the first binder.
