Verfahren zur Herstellung eines Bleiakkumulators Zusatz zu Patent ..... (Patentanmeldung P 20 08 982.1)Process for the production of a lead accumulator Addition to patent ..... (patent application P 20 08 982.1)
Das Hauptpatent betrifft eine Plattenanordnung eines Bleiakkumulators, bei der das Gitter mit einer porösen Umhüllung aus sauerstoff- und säurebeständigem Kunststoff umhüllt ist. Bei dem Ausführungsbeispiel des HauptpatentB wird als Umhüllung ein Beutel aus Gewebe verwendet, der eine gitterfÖrmige Plätte mit eingefüllter aktiver Masse dicht umhüllt. Hit einem derartigen Beutel können natürlich auch Rohrplatten umhüllt werden, bei denen die Akkumulatorplatte durch eine Reihe von parallel zueinander angeordneten Stäben gebildet wird, die an einem ihrer Enden miteinander übör einen Yerbiridungsstab mit Anschlußleiter verbunden sind.The main patent relates to a plate arrangement of a lead accumulator, in which the grid is covered with a porous cover made of oxygen- and acid-resistant plastic. In the embodiment of the main patent B, a bag made of fabric is used as a cover, which has a lattice-shaped The plate is tightly wrapped with the active compound. Tube plates can of course also be hit with such a bag are encased, in which the accumulator plate by a series of rods arranged parallel to one another is formed, which are connected to one another via a Yerbiridungsstab with connecting conductor at one of their ends.
Bekannt sind aus Glasfasermateriai und aus Kunststoffäden hergestellte Röhrchen, die über die Stäbe von Rohrplatten geschoben sind. Die aktive Masse wird in den ringförmigen Zwischenraum eingefüllt. "·Are known from Glasfasermateriai and from plastic threads manufactured tubes that are pushed over the rods of tube plates. The active mass is in the ring-shaped Filled in space. "·

Die Erfindung bezweckt eine Verbesserung des Herstellungsverfahrens eines Bleiakkumulators nach dem Hauptpatent. Insbesondere wird die Lebensdauer der verwendeten Umhüllung sowie deren Festigkeit und Widerstandsfähigkeit gegen Stöße und Schläge erhöht.The invention aims to improve the manufacturing process of a lead accumulator according to the main patent. In particular, the service life of the casing used is increased as well their strength and resistance to bumps and blows increases.
Biese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß alο Umhüllung Beutel, Rohrplattentaschen, Einzelröhrchen oder dergleichen aus gesintertem Kunststoff verwendet werden. Bas Wesen der Erfindung ist demnach darin zu sehen, daß nunmehr die Umhüllungen aus sauerstoff- und säurebeständigem, gesintertem Kunststoff hergestellt werden. Hierbei kann so vorgegangen werden, daß das betreffende Kunststoffmaterial in Mikrokörnungen in Sinterformen eingefüllt wird und im Sinter-Heißverfahren oder im Sinter-Kaltpreßverfahren zu einem offenen, mikroporösen Porengerüst in Form von Röhrchen, Rohrplattentaschen oder anderen Umhüllungen erzeugt wird.This object is achieved according to the invention in that alο Wrapping bags, tube plate bags, single tubes or the like made of sintered plastic can be used. The essence of the invention is therefore to be seen in the fact that now the casings are made of oxygen- and acid-resistant, sintered plastic. This can be done here be that the plastic material in question in Micro grains are filled in sintering molds and in the sintering hot process or in the sintering cold-pressing process to form an open, microporous pore structure in the form of tubes, tube plate pockets or other envelopes.
Bie Innenwände der Umhüllungen werden mit einem sauerstoff- und säurebeständigen Ionenleitmittel beschichtet. Durch diese Beschichtung wird die Ionenleitfähigkeit der Umhüllung und damit praktisch die Kapazität des betreffenden Akkumulators erhöht.The inner walls of the casings are sealed with an oxygen and acid-resistant ionic conductor coated. Through this Coating is the ionic conductivity of the envelope and thus practically the capacity of the battery in question elevated.
Als derartiges Ionenleitmittel kann beispielsweise Ligninsulfonat oder kolloidaler Graphit verwendet werden. As such Ionenleitmittel example lignin sulfonate or colloidal graphite can be used.
Da gemäß der Erfindung die Umhüllungen ia Sinterverfahren hergestellt werden, ist es nunmehr möglich, die Röhrchen oder Rohrplattentaschen bereits beim Sintern derart herzustellen, daß ihr eines Ende geschlossen ist. Sie besitzen dabei also etwa die Form von Fingerhüten mit entsprechend verlängerten Wandteilen. Gegenüber dem Herstellungsverfahren von Rohrplatten aus Glasfasern oder Kunatatoffasern entfällt somit ein Arbeitsgang, bei dem das entsprechende Ende mit einer gesonderten Kunststoffleiste zusätzlich abgeschlossen werdenSince, according to the invention, the casings are generally produced in a sintering process it is now possible to manufacture the tubes or tube plate pockets during sintering in such a way that that one end is closed to her. So they have about the shape of thimbles with appropriately elongated Wall parts. Compared to the manufacturing process for tube sheets made of glass fibers or Kunatoff fibers, this is no longer necessary an operation in which the corresponding end is also closed with a separate plastic strip

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert. Dabei ergeben sich weitere wichtige Merkmale der Erfindung aus der folgenden Beispielsbeschreibung. Es zeigt:The invention is illustrated below using an exemplary embodiment explained in more detail. Further important features of the invention emerge from the following description of the example. It shows:
Fig. 1 ein einseitig geschlossenes Einzelröhrchen1 shows a single tube closed on one side
aus gesintertem Kunststoff in perspektivischer Ansicht undmade of sintered plastic in perspective view and
Fig. 2 eine aus Einzelröhrchen nach Fig. 1 hergestellte Rohrplattentasche mit Ableitungsgitter. FIG. 2 shows a tube plate pocket made from individual tubes according to FIG. 1 with a drainage grid.
Das in Fig. 1 dargestellte Einzelröhrchen ist an seinem unteren Ende geschlossen. Es ist aus einem sauerstoff- und säurebeständigen Kunststoff, beispielsweise Polyäthylen, Polyester, Polyisobutylen, Polytetrafluoräthylen, Polytrifluorchloräthylen oder Polyvinylchlorid hergestellt. Der Kunststoff ist zu einem offenen, mikroporösen Porengerüst gesintert; dadurch wird eine ungehinderte Wanderung der Ionen und Säure durch die Umhüllung ermöglicht.The individual tube shown in Fig. 1 is closed at its lower end. It is made up of an oxygen and acid-resistant plastic, for example polyethylene, polyester, polyisobutylene, polytetrafluoroethylene, polytrifluorochloroethylene or polyvinyl chloride. The plastic is an open, microporous pore structure sintered; this enables unhindered migration of the ions and acid through the coating.
In die einseitig offenen Einzelröhrchen 1 der Fig. 1 sowie in die Rohrplattentaschen wird die aktive Masse eingefüllt. Die Einzelröhrchen sind zu einem Bleiplattengerüst vereinigt (vgl. Fig. 2).The active material is poured into the individual tubes 1 in FIG. 1, which are open on one side, and into the tube plate pockets. The individual tubes are combined to form a lead plate frame (see FIG. 2).
Die die Plattenanordnung bildenden Bleigitter besitzen an ihrem oberen Ende Verbreiterungen, die die Öffnungen 2 der Röhrchen dicht verschließen.The lead grids forming the plate assembly have at their upper end widenings that the openings 2 of Close the tube tightly.
