PATE-NT-ANSPRUCHrPATE-NT CLAIM no Verfahren zur Erhöhung der Leistungsfähigkeit von Depolarisationsmassen für galvanische Elemente, dadurch gekennzeichnet, daß man Metalloxyde, und zwar vornehmlich Oxyde solcher Metalle, welche in der elektrischen Spannungsreihe vom Zink nach der negativen Seite hin sich befinden (z. B. Wismutoxyd, Kupferoxyd, Silberoxyd, Quecksilberoxyd), auf den bekannten Mangansauerstoffverbindungen aus ihren Lösungen ausfällt oder chemisch mit ihnen verbindet und diese Produkte für sich oder als Zusatz anwendet.Process to increase the efficiency of depolarization masses for galvanic Elements, characterized in that there are metal oxides, especially oxides of those metals, which are in the electrical voltage series from zinc to the negative side (e.g. bismuth oxide, copper oxide, Silver oxide, mercury oxide), based on the known manganese oxygen compounds their solutions fail or chemically binds to them and these products for applies itself or as an add-on. nutzte dunkelbraune Manganihydroxyd verwendet oder das aus der Patentschrift 259999 bekannte tiefschwarze Mangansuperoxydhydrat. Als besonders vorteilhaft hat es sich herausgestellt, wenn man eine chemische Verbindung von Quecksilber und Mangan, nämlich mangansaures Quecksilberoxyd Hg Mn O4 zur Anwendung bringt. Diese Verbindung kann für sich oder aber zweckmäßig, zumal sie recht kostbar ist, mit Braunstein oder Manganoxydhydraten oder Mangansuperoxydhydraten vermengt werden, wie es natürlich auch bei den schon vorher gekennzeichneten Erzeugnissen geschehen kann. Als Elektrolyt dienen Lösungen, welche den Depolarisator nicht oder nur so weit angreifen, als zur Stromlieferung nötig ist. In der Hauptsache kommen daher Laugen der Alkalimetalle in Betracht.used dark brown manganese hydroxide or the deep black manganese peroxide hydrate known from patent 259999. It has been found to be particularly advantageous if a chemical compound of mercury and manganese, namely manganese-acid mercury oxide Hg Mn O 4 , is used. This compound can by itself or expediently, especially since it is very valuable, be mixed with manganese oxide or manganese oxide hydrates or manganese superoxide hydrates, as can of course also be done with the previously labeled products. The electrolyte used is solutions which do not attack the depolarizer or only attack it to the extent necessary to supply electricity. Bases of the alkali metals are therefore mainly used.
