Abstract
Description
Die Erfindung betrifft eine Batterie mit wenigstens einer von einem Gehäuse umgebenen, geschlossenen Einzelzellen und einer am Gehäuse angeordneten Überdrucksicherung.The The invention relates to a battery having at least one of one casing surrounded, closed individual cells and arranged on the housing overpressure protection.
Unter Batterie im Rahmen der vorliegenden Erfindung wird eine Einzelzelle oder ein Verbund von Einzelzellen oder eine zu Modulen zusammengefasste Anordnung von Einzelzellen verstanden, die in einem gemeinsamen Gehäuse angeordnet sind. Dieses Gehäuse kann sowohl wiederaufladbare als auch nicht wiederaufladbare Zellen umfassen. Insbesondere werden nachfolgend unter Batterien solche Batterien, wie z. B. Lithium- oder Lithium-Ionen-Batterien, verstanden, die Zellen enthalten, bei denen die Gefahr des Berstens und der Freisetzung von gefährlichen Substanzen, wie z. B. flüssige, brennbare Elektrolyte, besteht.Under Battery in the context of the present invention is a single cell or a composite of single cells or one grouped into modules Arrangement of single cells understood in a common casing are arranged. This case can be both rechargeable and non-rechargeable cells include. In particular, below batteries are those batteries, such as As lithium or lithium-ion batteries, understood that Contain cells where there is a risk of bursting and release of dangerous Substances, such. B. liquid, flammable electrolytes.
Derartige Batterien können unter starker Belastung oder bei Überlastung (z. B. bei Überladung oder zu hohem Entladestrom, beispielsweise bei einem Kurzschluss), im Schadensfall (z. B. Unfall, Elektrolytzersetzung) oder sogar im Normalbetrieb bei starker Erhitzung von außen in einen thermisch unkontrollierbaren Zustand geraten. Dabei können sie überhitzen, einen gefährlichen inneren Druck (auch Zelleninnendruck genannt) bis hin zum Bersten oder Explodieren der Zelle und des Gehäuses aufbauen, wodurch gefährliche Stoffe freigesetzt werden. Speziell im Bereich moderner Lithium- oder Lithium-Ionen-Batterien besteht eine besondere Gefährdung, da diese Batterien flüssige, brennbare, organische Elektrolyte enthalten. Diese Batterien können unter ungünstigen Umständen in Brand geraten und stellen ein sicherheitstechnisches Problem dar.such Batteries can under heavy load or overload (eg overcharged or overcharged) too high discharge current, for example in case of a short circuit), in Damage (eg accident, electrolyte decomposition) or even in the Normal operation with strong heating from the outside into a thermally uncontrollable State advised. They can overheat, a dangerous one internal pressure (also called internal cell pressure) up to bursting or explode the cell and build the housing, creating dangerous Substances are released. Especially in the field of modern lithium or lithium-ion batteries is a particular hazard, because these batteries are liquid, contain flammable, organic electrolytes. These batteries can be under unfavorable circumstances catch fire and pose a safety-related problem represents.
Um
Explosionen zu vermeiden, ist es bekannt, die Einzelzellen mit einer
gehäuseseitigen Überdrucksicherung
zu versehen. Als Überdrucksicherung
werden beispielsweise Überdruckventile oder
ein oder mehrere Sollbruchstellen oder eine oder mehrere Berstscheiben
am Gehäuse
angeordnet.
Nachteilig
dabei ist, dass die ober- bzw. unterhalb des Gehäuses
Der Erfindung liegt daher die Aufgabe zugrunde, eine Batterie mit mindestens einer von einem Gehäuse umgebenden Einzelzelle anzugeben, welche besonders sicher betrieben werden kann und welche im kritischen Betriebsfall einen sicheren und schnellen Druckabbau ermöglicht.Of the Invention is therefore the object of a battery with at least one of a housing specify surrounding single cell, which operated particularly safe and which can be a safe one in critical situations and rapid pressure reduction allows.
Hinsichtlich der Batterie wird die Aufgabe erfindungsgemäß gelöst durch die im Anspruch 1 angegebenen Merkmale. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Regarding the battery, the object is achieved by the in claim 1 specified characteristics. Advantageous developments of the invention are the subject of the dependent claims.
Bei der erfindungsgemäßen Batterie mit wenigstens einer von einem Gehäuse umgebenen, geschlossenen Einzelzelle und einer am Gehäuse angeordneten Überdrucksicherung ist diese in einen zwei Gehäuseseiten weitgehend umlaufend verbindenden Gehäuserahmen angeordnet. Durch eine Ausbildung des Gehäuses aus zwei Gehäuseseiten – einer oberen und einer unteren –, welche über einen seitlichen Gehäuserahmen umlaufend miteinander verbunden sind und eine Anordnung der Überdrucksicherung in diesen seitlichen Gehäuserahmen ist eine optimale Druckableitung und Gasableitung seitlich nach außen ermöglicht. Somit ist ein einfacher und definierter Abbau eines zu hohen Zelleninnendrucks zur Vermeidung einer Explosion sichergestellt. Darüber hinaus werden die im Zellinneren in Richtung der Überdrucksicherung strömenden Medien, wie z. B. Gase, weitgehend gedrosselt. Durch die seitliche Anordnung der Überdrucksicherung in den Gehäuserahmen weist eine aus mehreren einzelnen, übereinander gestapelten Batterien oder Batteriezellen gebildete Batterieflachzelle eine hohe Packungsdichte auf.at the battery of the invention with at least one enclosed by a housing, closed Single cell and one on the housing arranged overpressure protection this is in a two housing sides arranged largely circumferentially connecting housing frame. By an embodiment of the housing from two sides of the housing - one upper and a lower -, which over a side frame circumferentially interconnected and an arrangement of overpressure protection in this side frame is an optimal pressure discharge and gas discharge laterally Outside allows. Thus, a simple and defined degradation of too high a cell internal pressure to prevent explosion. Furthermore are the media flowing in the cell interior in the direction of overpressure protection, such as As gases, largely throttled. Due to the lateral arrangement the overpressure protection in the case frame has one of several individual, stacked batteries or battery cell battery cell formed a high packing density on.
Je nach Form, Größe und Abmessungen der Batterie kann die Überdrucksicherung durch zumindest einen oder mehrere in den Gehäuserahmen eingebrachte Berstbereiche gebildet sein.ever according to shape, size and dimensions The battery can be overpressure protection by at least one or more rupture areas introduced into the housing frame be formed.
In einer möglichen Ausführungsform ist die Überdrucksicherung im jeweiligen Berstbereich des Gehäuserahmens durch eine Vertiefung, eine Ausnehmung, eine Sollbruchstelle und/oder eine mit einer Sicherungsmembran versehene Öffnung gebildet.In a possible embodiment is the overpressure protection in the respective bursting region of the housing frame through a depression, a recess, a predetermined breaking point and / or one with a safety diaphragm provided opening educated.
Bevorzugt ist die Batterie eine Lithium- oder Lithium-Ionen-Batterie. Verglichen mit anderen Batterietypen besitzt eine Lithium- oder Lithium-Ionen-Batterie z. B. hohe Energiedichten, hohe Zellspannungen, geringe Gewichte, gute Leistungsdichten, geringe Selbstentladungen und hohe Zyklisierbarkeiten. Daher werden Lithium- oder Lithium-Ionen-Batterien insbesondere für mobile Anwendungen verwendet.Prefers the battery is a lithium or lithium-ion battery. Compared with other battery types has a lithium or lithium-ion battery z. High energy densities, high cell voltages, low weights, good power densities, low self-discharges and high cyclizability. Therefore, lithium or lithium-ion batteries are especially for mobile Applications used.
