Description

Verfahren zur Herstellung von Trockenelementen Zusatz zum Patent 446 o92 Die vorliegende Erfindung betrifft eine weitere Ausbildung des im Patent 446 o92 beschriebenen Trockenelements. In diesem Patent wird zur Erzielung der erforderlichen Isolierung der die positive Elektrode tragenden Metallunterlage gegen Einflüsse von Seiten des Elektrolvten die Zwischenlagerung eines selbständig abdichtenden Häutchens empfohlen. Diese Häutchen müssen aber, da sie ja selbst den Strom nicht leiten, an geeigneten Stellen durch leitende Kontaktmassen durchbrochen sein, welche die leitende Verbindung zwischen der Metallunterlage und der Kohleschicht bzw. dem Depolarisator bewerkstelligen, was nach dem Patent durch einfaches Zusammenpressen geschieht.Process for the production of dry elements Addition to patent 446 o92 The present invention relates to a further development of the 446 patent o92 described dry element. This patent is used to achieve the necessary Insulation of the metal base carrying the positive electrode against influences on the part of the electrolvte, the interim storage of an independently sealing one Cuticle recommended. But these membranes have to, because they do not have the electricity themselves conduct, be broken at suitable points by conductive contact masses, which the conductive connection between the metal base and the carbon layer or the Depolarizer accomplish what according to the patent by simply pressing together happens.

Unter Umständen erweist es sich als besonders zweckmäßig, diese durch das einfache - Zusammenpressen bewirkte leitende Verbindung zwischen Kohleelektrode und Metallunterlage inniger zu gestalten und ihren Übergangswiderstand zu verringern, indem man nach vorliegender Erfindung zwischen Metall und Kohleelektrode einen dritten Körper in Form einer körnigen Kontaktmasse, z. B. Kohlegries in gröberer oder feinerer Körnung, auf die vorher mit einem isolierenden und noch nicht ganz erhärteten, gut abdichtenden Überzug versehenen Kohleelektroden oder Depolarisatorbriketts bzw. auf -das so vorbehandelte Metall, zur Stromableitung dienend, hinaufbringt und durch Zusammenpressen, Walzen o. dgl. der drei Teile vereinigt. Dabei kann das Walzen und Pressen der Schichten bei gewöhnlicher oder erhöhter Temperatur vorgenommen werden.It may prove particularly useful to do this through the simple - compression brought about a conductive connection between the carbon electrode and metal base to make it more intimate and to reduce its contact resistance, by placing a third between the metal and carbon electrode according to the present invention Body in the form of a granular contact mass, e.g. B. Coarse grit in coarser or finer Grit, on which previously with an insulating and not yet fully hardened, good sealing coated carbon electrodes or depolarizer briquettes or on the metal pretreated in this way, used to conduct electricity, brings it up and through Pressing, rolling or the like of the three parts combined. This can roll and pressing the layers is carried out at ordinary or elevated temperature will.
