Beschreibung
Zusammenfassung:	A battery cell of a cylindrical structure includes a wound electrode assembly. An electrode plate of the electrode assembly includes a current collector, and the current collector includes a support layer and a conductive layer. In a thickness direction of the current collector, the conductive layer is disposed on at least one side of the support layer, and elongation of the support layer is greater than elongation of the conductive layer. In the thickness direction of the current collector, the support layer has a thickness greater than a total thickness of the conductive layer of the current collector.
