Description

Die Erfindung betrifft einen elektrischen Akkumulator, bei welchem sich zwischen; den Elektroden 'ein Trennungs organ befindet, durch das verhindert wird, daß sich die Elektroden berühren und so innere Kurzschlüsse bestehen. Gemäß der Erfindung besteht dieses Trennungsorgan aus agglutiniertem, gesponnenem Quarz.The invention relates to an electrical Accumulator, in which between; a separating organ is located near the electrodes, this prevents the electrodes touch and so there are internal short circuits. According to the invention this exists Separating organ made of agglutinated, spun quartz.

Es ist schon vorgeschlagen worden, statt der üblichen durchlochten Scheidewände aus isolierenden Stoffen, wie Hartgummi oder Celluloid oder aus porösem Stoff, die Scheidewände aus natürlichem Tripoli herzustellen. Scheidewände dieser Art haben gegenüber den Scheidewänden aus agglutiniertem gesponnenem Quarz verschiedene Nachteile. Insbesondere sind sie an eine bestimmte Porosität gebunden, also jeweils nur für einen bestimmten Akkumulatorentyp anwendbar, während man die Trennungsorgane nach der Erfindung in der Porosität beliebig ändern kann. Außerdem sind die Tripoliplatten nicht biegsam und elastisch wie die Platten nach der Erfindung , und lassen sich wegen ihrer erdigen Konsistenz schlecht handhaben; sie werden leicht bei Vibrationen bröcklig und müssen zur Vermeidung des Zerbröckeins mit den Elektroden zu einem einzigen Block verbunden werden.It has already been suggested to replace the usual perforated partitions insulating materials, such as hard rubber or celluloid or made of porous material, the partition walls made from natural tripoli. Partitions of this type have over the partitions made of agglutinated spun Quartz various disadvantages. In particular, they are tied to a specific porosity, i.e. only for a specific one Accumulator type applicable while using the separation organs according to the invention can change in the porosity at will. In addition, the tripoli plates are not flexible and elastic like the panels according to the invention, and can be because of their earthy consistency handle badly; they are easily crumbly when vibrated and need to Avoid crumbling with the electrodes connected to a single block will.

Es ist auch schon vorgeschlagen worden, für die Trennwände Glaswolle zu verwenden. Die Verwendung von Glaswolle hat aber den großen Nachteil, daß dadurch alkalische Salze in. den Elektrolyt gelangen, worunter derWirkungsgrad und die Lebensdauer der Akkumulatoren leiden.It has also been proposed to use glass wool for the partitions. The use of glass wool has the major disadvantage that it produces alkaline salts in. the electrolyte, including the efficiency and the life of the accumulators suffer.

Der gesponnene Quarz gemäß der Erfindimg kann auch auf der Oberfläche einer gewöhnlichen Scheidewand befestigt werden. Beispielsweise kann man eine Scheidewand aus Holz oder porösem Gummi, mit glatter oder gerippter Oberfläche, benutzen und auf einer Seite oder auf beiden Seiten den gesponnenen Quarz anbringen.The spun quartz according to the invention can also be on the surface of an ordinary Septum to be attached. For example, you can have a septum made of wood or porous rubber, with a smooth or ribbed surface, use and on Attach the woven quartz to one side or on both sides.

Auf die beschriebene Art erhält man ein kombiniertes Trennwanddiaphragma, das starr bleibt und ein leichtes Einsetzen gestattet. Dabei kann man eine beliebige Porosität des das Diaphragma bildenden Quarzes erlangen, indem man den Grad der Unterteilung des Quarzes und sein Verhältnis zum agglutinierenden Stoffe entsprechend wählt. Der Quarz kann* auch auf beiden Seiten der Scheidewand verschiedene Porosität erhalten.In the manner described, a combined partition diaphragm is obtained which is rigid remains and allows easy insertion. You can have any porosity of the quartz forming the diaphragm can be obtained by determining the degree of subdivision of the quartz and its ratio to the agglutinating substances is selected accordingly. Of the Quartz can * also have different porosities on both sides of the septum.
