Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine Batterie weist eine Anzahl von elektrisch seriell und/oder parallel miteinander verschalteten, einen Zellblock bildenden Einzelzellen auf, welche jeweils eine Elektrodenfolienanordnung aufweisen, die von einer folienartigen Hülle umgeben ist und die Einzelzellen zumindest abschnittsweise mit einem Vergusswerkstoff umhüllt sind. Erfindungsgemäß ist ein Halterahmen bestehend aus zwei Halbrahmen vorgesehen, wobei die Halbrahmen die Einzelzelle randseitig umlaufend angeordnet sind und zumindest eine in Richtung der Einzelzelle durchgehende Aussparung aufweisen, in welche der Vergusswerkstoff in einen zwischen einer Innenfläche des Halterahmens und einem umlaufenden Randbereich der Einzelzelle gebildeten Freiraum einfüllbar ist.A battery has a number of individual cells which are electrically connected in series and / or parallel to one another and form a cell block, which each have an electrode foil arrangement which is surrounded by a foil-like sheath and the individual cells are enveloped at least in sections with a casting material. According to the invention a holding frame is provided consisting of two half-frames, wherein the half frame the single cell peripherally arranged circumferentially and at least one in the direction of the single cell continuous recess, in which the casting material in a formed between an inner surface of the holding frame and a peripheral edge region of the single cell space can be filled is.
Mittels des in den Freiraum als Vergussraum eingefüllten Vergusswerkstoffes ist es in besonders vorteilhafter Weise möglich, die Einzelzelle auszurichten und somit eine Fixierung derselben in Bezug auf den Rahmen und auch den Zellblock zu verbessern. Zudem ist die Einzelzelle mittels des ausgehärteten Vergusswerkstoffes in ihrem Randbereich, in welchem sich im Allgemeinen eine Siegelnaht der Hülle befindet, insbesondere gegen ausdampfenden Elektrolyt zusätzlich abgedichtet.By means of the casting material filled into the free space as a potting space, it is possible in a particularly advantageous manner to align the individual cell and thus to improve its fixation with respect to the frame and also the cell block. In addition, the single cell is additionally sealed by means of the cured casting material in its edge region, in which there is generally a sealed seam of the shell, in particular against evaporating electrolyte.
Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung einer solchen Batterie.Furthermore, the invention relates to a method for producing such a battery.
