Description
Die Erfindung betrifft eine Batteriezelle mit einem Zellgehäuse und einem Folienwickel.The The invention relates to a battery cell with a cell housing and a foil wrap.
Üblicherweise weist eine Batterie zur Anwendung in Kraftfahrzeugen, insbesondere in Kraftfahrzeugen mit einem Hybridantrieb oder Brennstoffzellen-Fahrzeugen, mehrere elektrisch in Reihe und/oder parallel geschaltete Batteriezellen, beispielsweise Lithium-Ionen-Zellen, auf, wobei ein elektrischer Pol auf einem Zellgehäuse der Batteriezelle liegt.Usually has a battery for use in motor vehicles, in particular in motor vehicles with a hybrid drive or fuel cell vehicles, a plurality of battery cells connected electrically in series and / or in parallel, For example, lithium-ion cells, on, wherein an electrical Pol lies on a cell housing of the battery cell.
Dabei werden die Batteriezellen beispielsweise als Rundzellen ausgeführt, zu deren Herstellung Elektrodenfolien und zwischen diesen angeordnete Separatorfolien gestapelt und um einen Wickeldorn, z. B. ein hohles Rohr, gewickelt werden. An einer Oberseite und einer Unterseite eines dadurch gebildeten Folienwickels werden die Elektrodenfolien jeweils einer elektrischen Polarität miteinander elektrisch verbunden.there For example, the battery cells are designed as round cells, for the production of electrode films and arranged between them Separator foils stacked and a winding mandrel, z. B. a hollow Pipe, to be wrapped. At one top and one bottom a film roll formed thereby, the electrode films are respectively an electrical polarity electrically connected to each other.
Zur elektrischen Kontaktierung wird ein elektrischer Pol der Batteriezelle beispielsweise durch einen an die Oberseite des Folienwickels angebundenen Kupferableiter elektrisch isoliert durch einen Zellgehäusedeckel geführt. Die Unterseite des Folienwickels wird beispielsweise am Zellboden über einen zweiten Ableiter direkt mit dem Zellgehäuse verbunden, an dem somit der andere elektrische Pol anliegt.to electrical contact is an electrical pole of the battery cell for example, by a connected to the top of the film roll Copper conductor electrically insulated by a cell housing cover guided. The underside of the film wrap, for example on the cell floor via a second arrester directly to the Cell housing connected to the thus the other electrical Pole is applied.
Ferner
weist eine derartige Batterie üblicherweise eine Kühlplatte
auf, mittels derer Wärme aus der Batterie abführbar
ist. Dabei sind die Batteriezellen beispielsweise bodenseitig wie
in der
Derartige Batterien haben den Nachteil, dass sich die Batteriezellen beim Zusammenbau einer Batterie nicht berühren dürfen. Außerdem muss die Kühlplatte gegen die Batteriezellen elektrisch isoliert werden. Um gleichzeitig eine gute Wärmeleitung von den Batteriezellen zu der Kühlplatte zu erreichen, wird die Kühlplatte mit den Batteriezellen beispielsweise über eine elektrisch isolierende Kunststoffvergussmasse oder Wärmeleitfolie Wärme leitend verbunden. Kunststoffvergussmasse und Wärmeleitfolie sind teuer und insbesondere die Verwendung von Kunststoffvergussmasse ist auch fertigungstechnologisch aufwendig.such Batteries have the disadvantage that the battery cells during Do not touch the assembly of a battery. In addition, the cooling plate must be against the battery cells be electrically isolated. At the same time a good heat conduction from the battery cells to reach the cooling plate is the cooling plate with the battery cells, for example via an electrically insulating Kunststoffvergussmasse or heat conducting foil Heat conductively connected. Plastic grout and Wärmeleitfolie are expensive and in particular the use of plastic grout is also complex manufacturing technology.
Der Erfindung liegt daher die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Batteriezelle anzugeben.Of the Invention is therefore the object of an opposite state the prior art improved battery cell.
Die Aufgabe wird erfindungsgemäß durch eine Batteriezelle gelöst, welche die in Anspruch 1 angegebenen Merkmale aufweist.The Object is achieved by a battery cell having dissolved, which has the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Batteriezelle weist ein Zellgehäuse und einen Folienwickel mit um einen Wickeldorn gewickelten Elektrodenfolien zweier verschiedener Polaritäten auf. Die Elektrodenfolien einer ersten Polarität sind elektrisch leitend mit einem erstem elektrischen Kontaktelement verbunden und die Elektrodenfolien der zweiten Polarität sind elektrisch leitend mit einem zweitem elektrischen Kontaktelement verbunden, wobei die beiden elektrischen Kontaktelemente jeder Batteriezelle voneinander und von dem Zellgehäuse elektrisch isoliert sind.The Battery cell according to the invention has a cell housing and a foil wrap having electrode foils wound around a mandrel of two different polarities. The electrode foils a first polarity are electrically conductive with a first connected electrical contact element and the electrode films of the second polarity are electrically conductive with a second connected electrical contact element, wherein the two electrical contact elements each battery cell from each other and from the cell housing are electrically isolated.
Dies hat den Vorteil, dass keine Spannung am Zellgehäuse der Batteriezelle anliegt. Dadurch kann die Batteriezelle direkt an einer Kühlplatte angeordnet werden, ohne dass zwischen der Kühlplatte und der Batteriezelle ein elektrisch isolierendes und Wärme leitendes Material benötigt wird. Dies vereinfacht die Herstellung und reduziert die Herstellungskosten einer aus derartigen Batteriezellen aufgebauten Batterie durch den Wegfall elektrisch isolierenden und Wärme leitenden Materials und verbessert gegenüber bekannten Batteriezellen die Wärmeleitung zwischen der Kühlplatte und der Batteriezelle durch den direkten Kontakt der Kühlplatte mit der Batteriezelle.This has the advantage that no voltage on the cell body of the Battery cell is applied. This allows the battery cell directly to a cooling plate can be arranged without being between the cooling plate and the battery cell an electrically insulating and heat conductive material is needed. This simplifies production and reduces manufacturing costs a built-up of such a battery cell battery through the Elimination of electrically insulating and heat-conducting material and improves compared to known battery cells, the heat conduction between the cooling plate and the battery cell by the direct Contact of the cooling plate with the battery cell.
Ferner ist vorteilhaft, dass sich einzelne erfindungsgemäße Batteriezellen aufgrund ihres spannungsfreien Zellgehäuses berühren dürfen. Dadurch können die räumlichen Ausdehnungen einer aus derartigen Batteriezellen aufgebauten Batterie und somit der Bauraumbedarf für die Batterie verringert werden.Further is advantageous that individual inventive Battery cells due to their stress-free cell housing allowed to touch. This allows the spatial Expansions of a battery constructed from such battery cells and thus reduces the space requirement for the battery become.
Des Weiteren werden durch die Batteriezelle verursachte Gefahren verringert, da das Zellgehäuse nicht mehr einen elektrischen Pol der Batterie bildet und somit beispielsweise bei einem Platzen von Batteriezellen oder auslaufendem Elektrolytstoff weniger gefährlich als herkömmliche Batteriegehäuse ist.Of Furthermore, dangers caused by the battery cell are reduced, because the cell case is no longer an electrical pole of Battery forms and thus, for example, in a burst of battery cells or leaking electrolyte less dangerous than conventional battery case is.
Im Detail sind die Elektrodenfolien der ersten Polarität über ein erstes elektrisches Verbindungselement elektrisch leitend mit dem ersten elektrischen Kontaktelement verbunden und die Elektrodenfolien der zweiten Polarität über ein zweites elektrisches Verbindungselement elektrisch leitend mit dem zweiten elektrischen Kontaktelement verbunden.in the Detail are the electrode sheets of the first polarity about a first electrical connection element with electrically conductive connected to the first electrical contact element and the electrode films of the second polarity via a second electrical connection element electrically connected to the second electrical contact element.
Die elektrischen Verbindungselemente bestehen dabei vorzugsweise aus Weichkupfer oder lamelliertem Kupfer. Dies hat den Vorteil, dass die elektrischen Verbindungselemente eine hohe elektrische Leitfähigkeit aufweisen und gleichzeitig einfach formbar sind. Dabei sind die elektrischen Verbindungselemente an den zugehörigen Elektrodenfolien und/oder dem zugehörigen elektrischen Kontaktelement beispielsweise mittels Laserschweißung befestigt.The electrical connection elements are preferably made of soft copper or laminated copper. This has the advantage that the electrical connection elements have a high electrical Have conductivity and at the same time are easily malleable. In this case, the electrical connection elements are attached to the associated electrode films and / or the associated electrical contact element, for example by means of laser welding.
Vorzugsweise ist eines der elektrischen Verbindungselemente durch den Wickeldorn hindurch geführt und gegen den Wickeldorn elektrisch isoliert. Alternativ ist der Wickeldorn Teil eines der elektrischen Verbindungselemente und gegen den Folienwickel elektrisch isoliert. Dies hat den Vorteil, dass dadurch kein zusätzlicher Bauraum für die elektrischen Verbindungselemente erforderlich ist, da der Bauraum für den ohnehin benötigten Wickeldorn genutzt wird.Preferably is one of the electrical connection elements through the winding mandrel passed and electrically insulated against the winding mandrel. alternative the mandrel is part of one of the electrical connection elements and electrically insulated against the foil wrap. This has the advantage that thereby no additional space for the electrical connection elements is required, since the space used for the winding mandrel needed anyway becomes.
Bevorzugt weist jede Batteriezelle eine Ummantelung auf, die zur Ableitung von Wärme aus der Batteriezelle ausgebildet ist. Dabei hat die Ummantelung in einer Ebene senkrecht zu einer Längsachse der Batteriezelle vorzugsweise einen Querschnitt mit einer wabenförmigen äußeren Kontur. Dies hat den Vorteil, dass die größere der Ummantelung an den Ecken der wabenförmigen Kontur die Wärmeableitung durch die Ummantelung erhöht.Prefers each battery cell has a sheath which is for dissipation is formed of heat from the battery cell. there has the sheath in a plane perpendicular to a longitudinal axis of the Battery cell preferably has a cross section with a honeycomb outer Contour. This has the advantage that the larger the sheath at the corners of the honeycomb contour the Heat dissipation increased by the sheath.
