Abstract
A current collector for a bipolar electrode includes a first metal foil provided on one face, a second metal foil that is of a different kind from the first metal foil and that is provided on another face, and a conductive adhesive layer interposed between the first metal foil and the second metal foil, so as to bond the two together, in which an outer edge of the conductive adhesive layer is a dehydrating adhesive layer that undergoes a dehydration reaction when heated to 100° C. or higher.
Claims2
A current collector for a bipolar electrode, the current collector comprising:
- a first metal foil that is provided on one face;
- a second metal foil that is of a different kind from the first metal foil and that is provided on another face;
- and
- a conductive adhesive layer interposed between the first metal foil and the second metal foil, so as to bond the two together, wherein
- an outer edge of the conductive adhesive layer is a dehydrating adhesive layer that undergoes a dehydration reaction when heated to 100° C. or higher.
A recycling method of a current collector for a bipolar electrode, the recycling method comprising:
- heating the current collector according to claim 1 to 100° C. or higher, such that the dehydrating adhesive layer provided on the outer edge of the conductive adhesive layer interposed between the first metal foil and the second metal foil is evaporated or is expanded, creating a gap between the first metal foil and the second metal foil.
