WIPO Patent Application WO/2021/230008
Kind Code:
A1
Abstract:
This battery comprises: an electricity generation element having at least one unit cell including an electrode layer, a counter electrode layer, and an electrolyte layer positioned between the electrode layer and the counter electrode layer; and an insulating member that covers the electricity generation element. The insulating member is provided with: a first member that includes a first primary surface covering section that covers a first primary surface of the electricity generation element; and a second member that includes a second primary surface covering section that covers a second primary surface of the electricity generation element opposite to the first primary surface, the second member being joined to the first member. The joined section between the first member and the second member overlaps a side surface of the electricity generation element when viewed from a direction perpendicular to the side surface, and the elastic modulus of the first member is greater than the elastic modulus of the second member.
