Document Type and Number:
WIPO Patent Application WO/2022/163061
Kind Code:
A1
Abstract:
This power storage element comprises: a wound electrode body in which lithium manganate is contained as a main component in a positive electrode active material; and a container in which the wound electrode body is housed. The wound electrode body includes a composite layer formation portion in which a composite layer is formed and a composite layer non-formation portion which is positioned at least at one end in a first direction that is parallel to a winding axis. The ratio of the dimension of the wound electrode body in the first direction to the dimension of the wound electrode body in a second direction that is orthogonal to the first direction in a plan view is 1.45 or more.
