Description

Verfahren zur Herstellung eines Elektrolyten für Trockenbatterien. Der sogenannte »Elektrolyt« in Taschenbatterien besteht in der Regel aus r Teil Zinkchlorid, r Teil Weizenmehl und 2 Teilen Salmiak, wozu noch eine geringe Menge Ouccksilberghlorid kommt. Diese blasse, welche mit so viel Wasser angerührt wird, daß s'e einen gießfähigen Brei ergibt, bildet die Trennungsschicht zwischen der Kohlenmasse und dem Zinkbecher. Auch die Kohlenmasse, welche den eigentlichen Kohlenstift umgibt und selLst aus einer Mischung von Graphit und Braunstein besteht, enthält Salmiak oder andere hygroskopische Salze, mit denen sie fest um den Kohlenstift gepreßt wird.Process for the production of an electrolyte for dry batteries. The so-called "electrolyte" in pocket batteries usually consists of r part Zinc chloride, 1 part wheat flour and 2 parts ammonia, plus a small amount Ouccksilberghlorid is coming. This pale one, which is touched with so much water, that s'e results in a pourable slurry, forms the separating layer between the Coal mass and the zinc cup. Also the coal mass, which is the actual coal stick surrounds and itself consists of a mixture of graphite and manganese dioxide Salmiak or other hygroscopic salts with which they are firmly attached to the charcoal stick is pressed.

Es ist nun festgestellt worden, daß diese teuren Salze sowohl in der Kohlenmasse als Bindemittel als auch im Elektrolyten, der die »Kohle« umgibt, mehr oder weniger ersetzt werden können durch jenen Stoff, der bei der Papierfabrikation als Abfall entsteht, nämlich die sogenannte Sulfitablauge, die in eingedicktem Zustand auch unter dem Namen »Zeltpech« bekannt ist. Diese Ablauge entsteht bekanntlich beim Kochen des zerkleinerten Holzes mittels schwefligsauren Kalks und enthält die harzigen Extraktionsstoffe des Holze, wie Pektine, Lignineusw., als Schwefelverbindungen. Diese Lauge wirkt besonders in eingedickter Form nicht nur als gutes mechanisches Bindemittel der Kohlenmasse, sondern es hat sich auch gezeigt, daß sie anscheinend infolge ihres hohen Gehalts an Salzen und Kohlenstoffverbindungen als guter Elektrolyt und Vermittler des entstehenden Stromes zwischen der Kohle und dem Zink dient. Infolgedessen wird sie vorteilhaft als Zusatz zum Braunstein und teilweiser Ersatz des Graphits, als auch als Zusatz zum Elektrolyten und teilweiser Ersatz der in diesem enthaltenen Salze und des Mehls verwendet.It has now been found that these expensive salts are both in the Coal mass as a binding agent as well as in the electrolyte that surrounds the "coal", more or less can be replaced by the substance used in paper manufacture as waste arises, namely the so-called sulphite waste liquor, which is in a thickened state is also known under the name "Zeltpech". As is well known, this waste liquor is produced when cooking the crushed wood by means of sulphurous lime and contains the resinous extraction substances from wood, such as pectins, lignins, etc., as sulfur compounds. This lye works not only as a good mechanical one, especially in thickened form Binders of the coal mass, but it has also been shown that they appear to be good electrolyte due to their high content of salts and carbon compounds and acts as an intermediary for the resulting current between the carbon and the zinc. Consequently it is advantageous as an additive to brownstone and partial replacement of graphite, as well as an additive to the electrolyte and partial replacement of those contained in it Salts and flour used.

Es ist ohne weiteres einleuchtend, daß der wirtschaftliche Vorteil durch die Ersparnis an den jetzt gebräuchlichen teuren Stoffen sehr erheblich ist.It is readily apparent that the economic advantage is very considerable due to the savings on the expensive materials that are now in use.
