Title:
全固体二次電池用集電体、全固体二次電池用電極体および全固体二次電池
Document Type and Number:
Japanese Patent JP5521719
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a collector for all-solid-state secondary battery in which cracking and exfoliation occurring on the interface of an electrode active material layer and the collector due to temperature variation during use of the battery can be prevented.SOLUTION: The collector for all-solid-state secondary battery used in a all-solid-state secondary battery having an electrode active material layer containing an electrode active material and a solid-state electrolyte layer containing a solid-state electrolyte material has a collector substrate made of a metallic material, and a conductive thermal expansion relaxation layer formed on the collector substrate and having a heat expansion coefficient lower than that of the collector substrate but higher than that of the electrode active material layer.
