摘要: A battery cell (100) includes an electrode assembly (10) and a packaging bag (20). The electrode assembly (10) includes first electrode plates (11), second electrode plates (12) and separators (13). The first electrode plates (11) include two outer electrode plates (11a) and at least one inner electrode plate (11b) . In the first direction, the two outer electrode plates (11a) are disposed on two outermost sides of the electrode assembly (10) respectively, the inner electrode plate (11b) is disposed between the two outer electrode plates (11a), and the second electrode plates (12) are disposed between the two outer electrode plates (11a) . The packaging bag (20) includes a metal layer (21), and a relationship between a first strength S1 of the first current collectors (111) in the outer electrode plates (11a) and a second strength S2 of the metal layer (21) satisfies: 0.2 ≤ S1/S2 ≤ 0.5.

摘要: Die Erfindung betrifft ein Batteriezellgehäuse sowie ein Verfahren zur Herstellung eines erfindungsgemäßen Batteriezellgehäuses. Die Aufgabe der vorliegenden Erfindung, ein Batteriezellgehäuse mit einem Batteriezellgehäusemantel (1) mit zumindest bereichsweise rechteckigem Querschnitt anzugeben, welches sehr einfach gefertigt werden kann und gleichzeitig den Einsatz einer großen Breite an Aluminiumlegierungen zulässt, um auf unterschiedliche Anforderungen des Batteriezellgehäuses, beispielsweise erhöhte Festigkeitsanforderungen oder Wärmeleitfähigkeitsanforderungen, flexibel reagieren zu können, wird dadurch gelöst, dass das Batteriezellgehäuse einen rollgeformten Rohrkörper aus einer Aluminiumlegierung als Batteriezellgehäusemantel (1) aufweist, wobei der Batteriezellgehäusemantel (1) in Längsrichtung gefügt ist und zumindest bereichsweise einen rechteckigen Querschnitt aufweist, wobei der Batteriezellgehäusemantel (1) vorzugsweise aus einem Aluminiumlegierungsband (2) rollgeformt ist.
