Description
Die Erfindung bezieht sich auf eine Reservebatterie aus Anode und Kathode als Elektroden und einem Freiraum zur Aufnahme eines Elektrolyten gemäß dem Oberbegriff des Patentanspruches 1. Daneben bezieht sich die Erfindung auf ein Verfahren zum Herstellen einer solchen Reservebatterie.The The invention relates to a reserve battery of anode and cathode as electrodes and a space for receiving an electrolyte according to the preamble of claim 1. In addition, the invention relates to a Method for producing such a reserve battery.
Eine Reservebatterie ist eine Batterie, die typischerweise nur einmal nutzbar ist und die sich selbst durch Benetzung mit einem Elektrolyten aktiviert. Für eine Anwendung im medizinischen Bereich kann der Elektrolyt beispielsweise Körperflüssigkeit sein.A Backup battery is a battery that is typically only once is useable and that itself by wetting with an electrolyte activated. For an application in the medical field, for example, the electrolyte Be body fluid.
Reservebatterien sind bereits bekannt. Sie sind analog zu bekannten Primärbatterien aus Anode, Elektrolytraum und Kathode aufgebaut. Anders als bei solchen Primärbatterien ist allerdings bei Reservebatterien der Raum zwischen den Elektroden nicht mit Elektrolyt gefüllt. Erst bei Aktivierung wird der Zwischenraum mit ionisch leitfähigem Elektrolyten gefüllt.extra batteries are already known. They are analogous to known primary batteries composed of anode, electrolyte space and cathode. Unlike such primary batteries However, with reserve batteries the space between the electrodes is not filled with electrolyte. Only when activated is the gap with ionically conductive electrolyte filled.
Reservebatterien finden unter anderem Anwendung in Signallampen, beispielsweise Rettungswesten oder dergleichen, oder beispielsweise auch als Torpedoantrieb. In beiden Fällen werden sie durch eindringendes Seewasser aktiviert. Besonderer Vorteil von Reservebatterien ist die nahezu unbegrenzte Lagerfähigkeit, da durch den fehlenden Elektrolyten eine Selbstentladung im üblichen Sinne nicht möglich ist.reserve batteries find application in signal lamps, such as lifejackets or the like, or for example as a torpedo drive. In both cases they are activated by penetrating seawater. Special advantage of backup batteries is the almost unlimited shelf life, because by the missing electrolyte a self-discharge in the usual Senses not possible is.
Die bisher bekannten Systeme von Reservebatterien sind aus massiven Elektroden aufgebaut. Dadurch sind sie nicht geeignet für einen flachen Aufbau und solche Anwendungen, für die ein miniaturisierter Aufbau notwendig ist.The Previously known systems of backup batteries are made of solid Electrodes assembled. As a result, they are not suitable for one flat design and such applications, for which a miniaturized Construction is necessary.

auszubilden. Dies gilt beispiels weise für ein pyroelektrisches Dünnschichtsensorelement
gemäß der
Ausgehend von obigem Stand der Technik ist es Aufgabe der Erfindung, eine Reservebatterie zu schaffen, die kompakt aufgebaut und insbesondere auch preiswert ist.outgoing From the above prior art, it is an object of the invention, a Reserve battery to create, which is compact and, in particular, also is inexpensive.
Die Aufgabe ist erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Herstellungsverfahren für eine solche Reservebatterie sind in den nebengeordneten Ansprüchen 9 bis 11, 13 und 14 angegeben. Weiterbildungen der erfindungsgemäßen Reservebatterie und des zugehörigen Herstellungsverfahrens sind Gegenstand der Unteransprüche.The Task is inventively by the characterizing features of claim 1 solved. production method for one Such reserve battery are in the independent claims 9 to 11, 13 and 14 indicated. Further developments of the reserve battery according to the invention and the associated Manufacturing process are the subject of the dependent claims.
Die erfindungsgemäße Reservebatterie ist in Dünnschicht-Planartechnik mit Interdigitalstruktur und einzelnen Elektrodenfingern realisiert. Bei der bestimmungsgemäßen Anwendung schließen die Elektrodenfinger den Elektrolyten ein. Die somit gebildete Reservebatterie kann aufgrund ihres besonders einfachen Aufbaus auch sehr einfach hergestellt werden. Dadurch ist der Aufbau so preiswert, dass er insbesondere auch für sog. Disposable-Anwendungen, z.B. in der Medizindiagnostik, in Frage kommt.The Inventive backup battery is in thin-film planar technology realized with interdigital structure and individual electrode fingers. When used as intended shut down the electrode fingers enter the electrolyte. The thus formed backup battery can also be very simple due to its very simple structure getting produced. As a result, the structure is so cheap that he in particular also for so-called disposable applications, e.g. in medical diagnostics, in question comes.

Die Herstellung von dünnen Elektrodenschichten erfolgt vorteilhafterweise nach einem bekannten Siebdruckverfahren. Möglich ist es auch, die Elektroden mit einem Sprühverfahren auf ein Substrat aufzubringen. Gegebenenfalls kann dabei auf die Zwischenschicht des Kollektors verzichtet werden, sofern an die Elektroden direkt die Stromanschlüsse angebracht werden.The Production of thin Electrode layers are advantageously carried out according to a known Screen printing process. Possible it is also, the electrodes with a spray on a substrate applied. Optionally, it can be applied to the intermediate layer of the collector, provided that the electrodes directly the power connections attached become.
Derart dünne Schichten können auch beispielsweise mit einem angepassten Ink-Jet-Drucker erzeugt werden. Eine andere Möglichkeit für die Herstellung der Elektroden sind Druckverfahren, insbesondere der sogenannte Tampondruck oder dergleichen, weiterhin Tauchverfahren oder auch das sogenannte Schlickergießen.so thin layers can also created for example with a customized ink-jet printer become. Another possibility for the Production of the electrodes are printing processes, in particular the so-called pad printing or the like, further dipping method or the so-called Schlickergießen.
Nach
dem Prinzip der
Bei den beschriebenen Reservebatterien kann einer der beiden Elektroden, dem Elektrolytraum oder den darin enthaltenen porösen Körper, der den Separator darstellt, ein lösliches Salz zugesetzt werden. Dies kann entweder ein wasserlösliches, elektrisch leitendes Salz sein zur Befüllung mit Wasser oder wässrigen Lösungen oder aber auch ein Leitsalz für organische Flüssigkeiten.at The described reserve batteries can be one of the two electrodes, the electrolyte space or the porous body contained therein, the represents the separator, a soluble Salt are added. This can either be a water-soluble, be electrically conductive salt for filling with water or aqueous solutions or also a conductive salt for organic liquids.
Zur
Aktivierung anhand der
Als Elektrolyt sind alle Flüssigkeiten geeignet, die zumindest eine geringfügige ionische Leitfähigkeit aufweisen. Bei einer medizinischen Anwendung kann dies eine Körperflüssigkeit, wie Blut, Urin oder Speichel, sein.When Electrolyte are all liquids suitable, the at least a slight ionic conductivity exhibit. In a medical application, this may be a body fluid, like blood, urine or saliva.
Der Elektrolyt kann auch direkt die zu analysierende Flüssigkeit sein. Dies ist vorteilhaft für den Einsatz von sogenannten Disposable-Anwendungen in der Medizintechnik. Für solche Disposable-Anwendungen ist ein ultradünner Aufbau mit geringem Materialeinsatz und die einfache Fertigung vorteilhaft.Of the Electrolyte can also directly the liquid to be analyzed be. This is beneficial for the use of so-called disposable applications in medical technology. For such Disposable applications is an ultra-thin design with low material usage and the ease of manufacture advantageous.
Bei Kontakt mit einer Flüssigkeit aktiviert sich die Batterie und die damit verbundene elektronische Schaltung selbstständig. Die Aktivierung durch die Analyseflüssigkeit wirkt also wie ein intelligenter Schalter.When in contact with a liquid, the battery and the electronic circuit connected to it activates automatically. Activation by the analysis fluid thus acts as a smart one Switch.
