Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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, 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 a first electrolyte extension portion and a second 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, respectively; and an insulating fixing member that includes a current-collector covering portion and a fixing portion, the current-collector covering portion 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, the fixing portion is disposed between an inner surface of the current-collector covering portion of the insulating fixing member and an outer surface of the distal end portion of the current-collector extension portion, the fixing portion fixes the insulating fixing member to the distal end portion of the current-collector extension portion, wherein the insulating fixing member covers only the second electrolyte extension portion out of first electrolyte extension portion and the second electrolyte extension portion. 2. The electrode body according to claim 1 , wherein the fixing member covers an overall distal end portion of the current-collector extension portion. 3. The electrode body according to claim 1 , wherein the fixing member becomes thinner toward one end of the fixing member.
