    Elektrode, insbesondere für Elektrolyt-Kondensatoren.   
 EMI1.1 
 Aufrauhung auf mechanischem   Wege   durch Sandstrahlen durch Feilenhiebe und ähnliche Mittel oder durch Ätzung auf chemischem Wege vergrössert wird. 



   Die Erfindung bezieht sich demgegenüber auf eine Elektrode, insbesondere für ElektrolytKondensatoren, und bezweckt. eine möglichst grosse   Oberfläche   pro Gewichtseinheit bei etwa konstanter Stärke zu erhalten. Dies wird gemäss der Erfindung dadurch erreicht, dass die Elektrode aus einem   Grundmetall   und einer äusseren Schicht aus Metall besteht, von denen das eine   Metall porös   
 EMI1.2 
 und ähnliche elektrolytische Apparate verwendbar. Die erzielte Raumersparnis ist um so grösser, je höher das Verhältnis der aktiven Oberfläche zur normalen Oberfläche    ist.   



   Eine weitere Möglichkeit, eine Elektrode nach der Erfindung herzustellen, besteht darin, dass das wirksame Elektrodenmetall auf die poröse Oberfläche eines inaktiven   Grundkörpers,   z. B. Kupfer. 
 EMI1.3 
 Kondensation aufgebracht ist. 



   PATENT-ANSPRÜCHE :   l.   Elektrode, insbesondere für Elektrolyt-Kondensatoren, dadurch gekennzeichnet, dass sie aus   einem Grundmetall und   einer äusseren Schicht aus Metall besteht, von denen das eine Metall porös ist.

    Electrode, especially for electrolytic capacitors.
 EMI1.1
 Roughening is increased mechanically by sandblasting with file cuts and similar means or by chemical etching.



   In contrast, the invention relates to an electrode, in particular for electrolytic capacitors, and aims. to obtain as large a surface as possible per unit weight with approximately constant strength. According to the invention, this is achieved in that the electrode consists of a base metal and an outer layer made of metal, one of which is porous metal
 EMI1.2
 and the like electrolytic apparatus can be used. The space saving achieved is greater, the higher the ratio of the active surface to the normal surface.



   Another possibility of producing an electrode according to the invention is that the active electrode metal is applied to the porous surface of an inactive base body, e.g. B. Copper.
 EMI1.3
 Condensation is applied.



   PATENT CLAIMS: l. Electrode, in particular for electrolytic capacitors, characterized in that it consists of a base metal and an outer layer of metal, one of which is porous metal.
