Akkumulatoraccumulator
Die Erfindung betrifft einen neuen Akkumulator.The invention relates to a new accumulator.
In der deutschen Patentanmeldung P 19 38 409·9-45 ist die Verwendung von Titannitrid, das durch Umsetzung von Stickstoff mit Titan hergestellt wurde, als den negativen Reaktionsteilnehmer Bleiperoxyd tragende Akkumulatorplatte in Blei/Schwefelsäure-Akkumulatoren beschrieben. Hierbei wird vor dem Aufbringen der pastenartigen Oxydmischung eine dünne Schicht aus einem nicht-polarisierenden Element, beispielsweise Gold oder Blei, auf die Oberfläche des Titannitrid-Körpers aufgetragen. Das Titannitrid ist in dem Schwefelsäureelektrolyten nicht löslich. Metallisches Titan ist als solches in der Schwefelsäure löslich, wobei innerhalb kurzer Zeit eine violette Lösung von Titansulfat in der Säure gebildet wird.In the German patent application P 19 38 409 · 9-45 is the Use of titanium nitride, made by reacting nitrogen with titanium, as the negative reactant Accumulator plate carrying lead peroxide described in lead / sulfuric acid accumulators. Here is before applying the paste-like oxide mixture, a thin layer of a non-polarizing element, for example Gold or lead, on the surface of the titanium nitride body applied. The titanium nitride is not soluble in the sulfuric acid electrolyte. Metallic titanium is as such soluble in sulfuric acid, being within a purple solution of titanium sulfate is formed in the acid for a short time.
Es hat sich nun gezeigt, daß Schwefelsäure mit darin gelöstem Titanylsulfat (TiOSO4-H2SO^-SH2O) einen klaren farb-It has now been shown that sulfuric acid with dissolved titanyl sulfate (TiOSO 4 -H 2 SO ^ -SH 2 O) has a clear color
