Document Type and Number:
WIPO Patent Application WO/2018/181575
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an all-solid-state lithium ion secondary battery which does not undergo a decrease in the battery capacity caused by absorption of moisture from the air, thereby having high reliability. An all-solid-state lithium ion secondary battery which is provided with a battery element that comprises an electrolyte layer between a positive electrode layer and a negative electrode layer, a pair of terminal electrodes that are respectively connected to the positive electrode layer and the negative electrode layer at both end portions of the battery element, and a moisture-proofing layer that is arranged on surfaces other than the surfaces serving as the terminal electrodes. This all-solid-state lithium ion secondary battery is characterized in that the moisture-proofing layer contains a cured product of a composition that contains a polymer compound and metal compound particles.
