Abstract
A power storage device is provided with an electrode body and an outer package in which the electrode body is sealed. The outer package includes an outer package film which enfolds the electrode body in such a manner that an opening is formed, and a cover member which is disposed at the position of the opening. The cover member has a first surface that faces the electrode body, a second surface that is on the reverse side of the first surface, and a projection that protrudes from the second surface.
Claims15
An electrical storage device comprising:
- an electrode assembly;
- and
- an outer packaging that seals the electrode assembly,
- wherein
- the outer packaging includes
- an outer package film that wraps the electrode assembly to form an opening part, and
- a lid that is disposed at the opening part, and
- the lid includes
- a first surface that faces the electrode assembly,
- a second surface on a side opposite to the first surface, and
- at least either a protrusion that protrudes from the second surface or a recessed portion that is recessed from the second surface toward the first surface.
A method for manufacturing an electrical storage device including
- an electrode assembly, and
- an outer packaging that seals the electrode assembly,
- the outer packaging including
- an outer package film that wraps the electrode assembly to form an opening part, and
- a lid that closes the opening part,
- the lid including
- a first surface that faces the electrode assembly,
- a second surface on a side opposite to the first surface, and
- at least one of a protrusion that protrudes from the second surface and a recessed portion that is recessed from the second surface toward the first surface,
- the method for manufacturing the electrical storage device comprising fixing a position of the lid with respect to the electrode assembly by fixing a jig to at least one of the protrusion and the recessed portion of the lid disposed on a lateral side of the electrode assembly.
A transport jig for an electrode assembly comprising:
- at least a pair of plates that sandwiches the electrode assembly;
- and
- a coupling portion that couples the pair of plates.
