Description
Die Erfindung betrifft eine Batterie mit einem Batteriezellenstapel, der mehrere elektrisch miteinander verschaltete und hintereinander angeordnete Batteriezellen umfasst. Die Batteriezellen des Batteriezellenstapels sind dabei als so genannte Pouchzellen, die auch als Coffeebagzellen bezeichnet werden, ausgebildet, die jeweils eine von einer beutelartig ausgebildeten Hülle umgebene elektrochemisch aktive Elektrodenfolienanordnung aufweisen.The invention relates to a battery with a battery cell stack, which comprises a plurality of electrically interconnected and successively arranged battery cells. The battery cells of the battery cell stack are designed as so-called pouch cells, which are also referred to as Coffeebagzellen, each having a surrounded by a bag-like envelope electrochemically active electrode foil arrangement.
Beim Betrieb einer derartigen Batterie erwärmen sich die Pouchzellen und es kommt zu einer thermischen Ausdehnung und Verformung der Pouchzellen. Zur Bildung des Zellverbundes werden die Pouchzellen üblicherweise jeweils in einem Rahmen gehalten und mehrere Batteriezellenrahmen durch geeignete Spannelemente, z. B. durch Schrauben und/oder Andruckleisten, zusammengehalten. Bei der Ausführung der Batteriezellenrahmen ist es wichtig, deren thermische Ausdehnung auf die der Spannelemente abzustimmen.During operation of such a battery, the pouch cells heat up and there is a thermal expansion and deformation of the pouch cells. To form the cell composite, the pouch cells are usually each held in a frame and several battery cell frame by suitable clamping elements, for. B. held together by screws and / or pressure bars. In the design of the battery cell frame, it is important to match their thermal expansion to that of the clamping elements.
Zur Ableitung der beim Betrieb entstehenden Wärme und zur Polsterung der Pouchzellen gegen mechanische Erschütterungen und Vibrationen werden häufig geeignete Materialien zwischen den einzelnen Pouchzellen angeordnet. Beispielsweise offenbart
Der Erfindung liegt die Aufgabe zu Grunde, eine insbesondere hinsichtlich des Gewichts und der Kosten des Aufbaus verbesserte Batterie mit einem Batteriezellenstapel aus so genannten Pouchzellen anzugeben.The invention is based on the object of specifying a battery which is improved, in particular with regard to the weight and the cost of the construction, with a battery cell stack of so-called pouch cells.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine erfindungsgemäße Batterie weist einen Batteriezellenstapel auf, der mehrere elektrisch miteinander verschaltete und hintereinander angeordnete Batteriezellen umfasst, die jeweils eine von einer beutelartig ausgebildeten Hülle umgebene elektrochemisch aktive Elektrodenfolienanordnung aufweisen. Um den Batteriezellenstapel ist wenigstens teilweise ein Spannband herumgeführt, das batteriezellenseitig mit einem Klebstoff beschichtet ist.A battery according to the invention has a battery cell stack which comprises a plurality of battery cells which are electrically interconnected and arranged one behind the other, each having an electrochemically active electrode foil arrangement surrounded by a pouch-like shell. To the battery cell stack is at least partially led around a tension band, the battery cell side is coated with an adhesive.
Durch das Spannband werden die Batteriezellen des Batteriezellenstapels verspannt und zusammengehalten. Gegenüber einem nicht klebenden Spannelement werden die Batteriezellen vorteilhaft zusätzlich durch die Klebung fixiert. Durch die gegenüber einem nicht klebenden Spannelement erheblich höhere Haftreibung des mit dem Klebstoff beschichteten Spannbandes wird die aufgebrachte Spannkraft dabei über die ganze Länge des Spannbandes verteilt.By the strap, the battery cells of the battery cell stack are braced and held together. Compared to a non-adhesive clamping element, the battery cells are advantageously additionally fixed by the bond. By compared to a non-adhesive clamping element considerably higher static friction of the adhesive coated with the clamping band, the applied clamping force is distributed over the entire length of the clamping band.
