Abstract
(EN)
Provided is an all-solid-state secondary battery with high uniformity of heat dissipation for heat generated by a battery reaction. An all-solid-state lithium ion secondary battery (100) comprises a laminate (5) that has a positive electrode layer (1) including a positive electrode current collector layer (1A) and a positive electrode active material layer (1B), a negative electrode layer (2) including a negative electrode current collector layer (2A) and a negative electrode active material layer (2B), a solid electrolyte layer (3) including a solid electrolyte, and a a solid-electrolyte-containing margin layer (4) disposed side-by-side with each of the positive electrode layer (1) and the negative electrode layer (2). The positive electrode layer (1) and the negative electrode layer (2) are alternatingly laminated in the laminate (5) with the solid electrolyte layer (3) containing a solid electrolyte interposed therebetween. In the laminate (5), metal particles (10) having an oxide film are included in the positive electrode active material layer (1B), the negative electrode active material layer (2B), the solid electrolyte layer (3), and the margin layer (4).
