Abstract

A method of producing an electric storage device includes a fastening that includes fastening a laminate that includes a lithium foil and a metal foil to at least one of a first separator and a second separator using a bonding member, and a winding that includes winding the first separator, the second separator, the laminate, a cathode, and an anode to obtain a wound element, one of the first separator and the second separator being disposed between the cathode and the anode.

Claims (7)

1. A method of producing an electric storage device comprising:

a fastening that includes fastening a laminate that includes a lithium foil and a metal foil to at least one of a first separator and a second separator using a bonding member; and

a winding that includes winding the first separator, the second separator, the laminate, a cathode, and an anode to obtain a wound element, one of the first separator and the second separator being disposed between the cathode and the anode,

wherein the bonding member comes in contact with the metal foil, but is spaced apart from the lithium foil.

2. The method of producing an electric storage device according to claim 1 , wherein the fastening includes providing the bonding member on the laminate on a side of a lead end.

3. The method of producing an electric storage device according to claim 1 , further comprising placing the wound element in a container, and injecting an electrolytic solution into the container.

4. The method of producing an electric storage device according to claim 3 , further comprising doping lithium ions into the anode by short-circuiting the laminate and the anode.
