摘要:
An electrode assembly with improved connection between current collectors and electrode tabs, and a method for manufacturing the same, for assuring safety with respect to overcharge, and battery capacity by improving a connection structure between the electrode tab and the current collector are provided. The electrode assembly for a rechargeable battery includes: an electrode current collector; an uncoated region in which an electrode active material layer is not formed, and provided on one side of the electrode current collector; an electrode tab disposed in the uncoated region; and a conductive adhesion portion that is disposed between the uncoated region and the electrode tab. The conductive adhesion portion comprises a positive temperature coefficient (PTC) material.
