ELECTRODE BODY

摘要

An electrode body includes a laminated body and an insulating fixing member. The laminated body includes a positive-electrode active material layer, a negative-electrode active material layer, a negative-electrode current collector layer, and a solid electrolyte layer. The negative-electrode current collector layer includes a current-collector extension portion that extends outward further than the negative-electrode active material layer. The solid electrolyte layer includes an electrolyte extension portion that integrally covers an end surface of the negative-electrode active material layer and a base end portion of the current-collector extension portion. The insulating fixing member covers at least front and back surfaces of a distal end portion exposed from the second electrolyte extension portion.

1. An electrode body, comprising:
a laminated body that includes a positive electrode layer, a negative electrode layer, a positive-electrode current collector layer, a negative-electrode current collector layer, and a solid electrolyte layer, wherein the positive-electrode current collector layer or the negative-electrode current collector layer includes a current-collector extension portion that extends outward further than the positive electrode layer or the negative electrode layer, the solid electrolyte layer includes an electrolyte extension portion that integrally covers an end surface of the positive electrode layer or the negative electrode layer and a base end portion of the current-collector extension portion; and an insulating fixing member that covers at least front and back surfaces of a distal end portion of the current-collector extension portion, the distal end portion being exposed from the electrolyte extension portion.
