Description
Die Erfindung betrifft eine Batteriezelle und einen Zellblock mit Batteriezellen.The invention relates to a battery cell and a cell block with battery cells.
Es sind bereits Batteriezellen mit zumindest zwei Hüllblechen und mit zumindest einem die Hüllbleche verbindenden Rahmenelement bekannt.There are already known battery cells with at least two cladding sheets and at least one frame element connecting the cladding sheets.
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine Batteriezelle mit einem geringen Bauraumbedarf bereitzustellen. Sie wird durch eine erfindungsgemäße Ausgestaltung entsprechend dem Anspruch 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is in particular the object of providing a battery cell with a small space requirement. It is achieved by an embodiment according to the invention according to claim 1. Further developments of the invention will become apparent from the dependent claims.
Die Erfindung geht aus von einer Batteriezelle, insbesondere für eine Hochvolt-Kraftfahrzeugbatterie, mit zumindest zwei Hüllblechen und mit zumindest einem die Hüllbleche verbindenden Rahmenelement.The invention is based on a battery cell, in particular for a high-voltage motor vehicle battery, with at least two cladding sheets and with at least one frame element connecting the cladding sheets.
Es wird vorgeschlagen, dass die Batteriezelle eine außen liegende Diffusionssperre aufweist, die die Hüllbleche und das zumindest eine Rahmenelement zumindest teilweise nach außen überdeckt und die dazu vorgesehen ist, ein Diffundieren von Wasserdampf durch das zumindest eine Rahmenelement in ein Zellinneres zu verhindern. Dadurch kann das Rahmenelement bezüglich einer Breite so ausgelegt werden, dass lediglich ein Elektrolytaustritt aus dem Zellinneren verhindert wird. Das Rahmenelement muss nun nicht mehr eine Dicke aufweisen, die eine Eindringtiefe von Wasserdampf in ein Material des Rahmenelements übersteigt, um ein Diffundieren von Wasserdampf durch das Rahmenelement zu verhindern. Ein Bauraumbedarf des Rahmenelements kann somit verringert werden. Es können für die außen liegende Diffusionssperre Materialien gewählt werden, die nicht elektrisch isolierend wirken. Dadurch können elektrisch leitende Materialien für die Diffusionssperre ausgewählt werden, die ein Diffundieren von Wasserdampf bei geringeren Materialdicken als elektrisch isolierende Materialien verhindern. Dadurch kann eine dünnere Diffusionssperre erreicht werden. Ein Bauraumbedarf für die Batteriezelle kann damit verringert werden. Unter einem „Hüllblech” soll insbesondere ein aus einem Blech geformtes Batteriegehäuseteil verstanden werden, das dazu vorgesehen ist, ein Zellinneres zur Aufnahme eines elektrochemisch aktiven Teils der Batteriezelle auf zumindest einer Seite zu begrenzen. Vorzugsweise sind die Hüllbleche aus einem elektrisch leitenden Material. Die Hüllbleche können je nach Anforderungen in Form einer Platte, in Form einer Schale oder einer anderen geeigneten Form ausgeführt sein. Unter einem „Rahmenelement” soll insbesondere ein zwischen den Hüllblechen angeordnetes Batteriegehäuseteil verstanden werden, das dazu vorgesehen ist, die Hüllbleche mechanisch miteinander zu verbinden. Vorzugsweise ist das Rahmenelement aus einem elektrisch isolierenden Material hergestellt.It is proposed that the battery cell has an external diffusion barrier which at least partially covers the enveloping plates and the at least one frame element outwards and which is intended to prevent a diffusion of water vapor through the at least one frame element into a cell interior. As a result, the frame element can be designed with respect to a width so that only an electrolyte leakage from the cell interior is prevented. The frame element no longer has to have a thickness which exceeds a penetration depth of water vapor into a material of the frame element in order to prevent diffusion of water vapor through the frame element. A space requirement of the frame member can thus be reduced. It can be selected for the outer diffusion barrier materials that do not act electrically insulating. As a result, electrically conductive materials for the diffusion barrier can be selected, which prevent diffusion of water vapor at lower material thicknesses than electrically insulating materials. As a result, a thinner diffusion barrier can be achieved. A space requirement for the battery cell can thus be reduced. A "cladding sheet" is to be understood in particular as a battery housing part formed from a sheet metal, which is intended to limit a cell interior to accommodate an electrochemically active part of the battery cell on at least one side. Preferably, the cladding sheets of an electrically conductive material. The cladding can be made in the form of a plate, in the form of a shell or other suitable form depending on requirements. A "frame element" is to be understood in particular a arranged between the Hüllblechen battery housing part, which is intended to mechanically connect the Hüllbleche each other. Preferably, the frame member is made of an electrically insulating material.
Des Weiteren wird vorgeschlagen, dass die Diffusionssperre eine Metallfolie umfasst, die dazu vorgesehen ist, ein Diffundieren von Wasserdampf in das Zellinnere zu verhindern. Dadurch kann eine besonders dünne Diffusionssperre erreicht werden. Ein Bauraumbedarf für die Batteriezelle kann damit verringert werden. Unter einer „Metallfolie” soll in diesem Zusammenhang ein flaches Blech aus einem Metall verstanden werden, das eine maximale Dicke von 0,2 mm, vorteilhaft eine maximale Dicke von 0,1 mm aufweist.Furthermore, it is proposed that the diffusion barrier comprises a metal foil, which is intended to prevent a diffusion of water vapor into the cell interior. As a result, a particularly thin diffusion barrier can be achieved. A space requirement for the battery cell can thus be reduced. In this context, a "metal foil" is to be understood as meaning a flat metal sheet which has a maximum thickness of 0.2 mm, advantageously a maximum thickness of 0.1 mm.
Weiterhin wird vorgeschlagen, dass die Batteriezelle ein Isolierungselement umfasst, das zur elektrischen Isolierung zumindest zwischen der Diffusionssperre und den Hüllblechen angeordnet ist. Dadurch kann ein Kurzschluss der Batteriezelle sicher vermieden werden und somit eine Beschädigungsanfälligkeit der Batteriezelle vermindert werden.Furthermore, it is proposed that the battery cell comprises an insulation element, which is arranged for electrical insulation at least between the diffusion barrier and the Hüllblechen. As a result, a short circuit of the battery cell can be safely avoided and thus a susceptibility to damage of the battery cell can be reduced.
Ferner wird vorgeschlagen, dass das zumindest eine Rahmenelement das Isolierungselement ausbildet. Dadurch kann eine Bauteilanzahl reduziert werden. Ferner kann ein Montageprozess der Batteriezelle beschleunigt werden, da eine separate Montage eines Isolierungselements entfällt.It is also proposed that the at least one frame element forms the insulation element. This can reduce a number of components. Furthermore, an assembly process of the battery cell can be accelerated because a separate mounting of an insulation element is eliminated.
Weiterhin wird vorgeschlagen, dass die Diffusionssperre eine thermoplastische Schicht aufweist, die dazu vorgesehen ist, unter Hitze und Druck mit dem Isolierungselement verbunden zu werden. Dadurch kann eine besonders einfach zu montierende Diffusionssperre erreicht werden.Furthermore, it is proposed that the diffusion barrier has a thermoplastic layer, which is intended to be connected to the insulating element under heat and pressure. This allows a particularly easy to install diffusion barrier can be achieved.
Die Erfindung betrifft ferner einen Zellblock mit Batteriezellen, die zumindest zwei Hüllbleche und zumindest ein die Hüllbleche verbindendes, elektrisch isolierendes Rahmenelement aufweisen. Es wird vorgeschlagen, dass der Zellblock zumindest eine außen liegende Diffusionssperre aufweist, die die Hüllbleche und das zumindest eine Rahmenelement zumindest teilweise nach außen abdeckt und die dazu vorgesehen ist, ein Diffundieren von Wasserdampf durch das zumindest eine Rahmenelement in ein Zellinneres zu verhindern. Dadurch kann das zumindest eine Rahmenelement bezüglich einer Breite so ausgelegt werden, dass lediglich ein Elektrolytaustritt aus dem Zellinneren verhindert wird, nicht jedoch zusätzlich ein Diffundieren von Wasserdampf durch das zumindest eine Rahmenelement durch die Breite des zumindest einen Rahmenelements verhindert wird. Dadurch kann ein Bauraumbedarf des zumindest einen Rahmenelements verringert werden. Es können für die außen liegende Diffusionssperre Materialien gewählt werden, die nicht elektrisch isolierend wirken. Dadurch können elektrisch leitende Materialien für die Diffusionssperre ausgewählt werden, die ein Diffundieren von Wasserdampf bei geringeren Materialdicken als elektrisch isolierende Materialien verhindern. Dadurch kann eine dünnere Diffusionssperre erreicht werden. Ein Bauraumbedarf für die Batteriezelle kann damit verringert werden.The invention further relates to a cell block with battery cells which have at least two enveloping plates and at least one electrically insulating frame element connecting the enveloping plates. It is proposed that the cell block has at least one outer diffusion barrier which at least partially covers the cladding sheets and the at least one frame element outwards and which is intended to prevent a diffusion of water vapor through the at least one frame element into a cell interior. As a result, the at least one frame element can be designed with respect to a width so that only an electrolyte leakage from the cell interior is prevented, but not additionally a diffusion of water vapor through the at least one frame element is prevented by the width of the at least one frame element. As a result, a space requirement of the at least one frame element can be reduced. It can be selected for the outer diffusion barrier materials that do not act electrically insulating. As a result, electrically conductive materials for the diffusion barrier can be selected, the one Avoid diffusion of water vapor at lower material thicknesses than electrically insulating materials. As a result, a thinner diffusion barrier can be achieved. A space requirement for the battery cell can thus be reduced.
