PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine Metallelektrode für galvanische Elemente sowie Sammler, welche bei geringem Gewicht eine verhältnismäßig große Oberfläche besitzt und bei sparsamem Verbrauch an Metall die erforderliche Leitfähigkeit und Haltbarkeit ergibt. Die Elektrode ist hauptsächlich für die Anwendung als Lösungselektrode (negative Polelektrode) in Elementen bestimmt undThe present invention relates to a metal electrode for galvanic elements as well Collector, which has a relatively large surface area and low weight results in the required conductivity and durability with economical consumption of metal. The electrode is mainly used as a solution electrode (negative Pole electrode) in elements and
ίο kann aus irgendeinem geeigneten Metall (Zink, Magnesium, Cadmium usw.) bestehen.ίο can be made of any suitable metal (zinc, Magnesium, cadmium, etc.).
Während man bisher für den Zweck, mit verhältnismäßig wenig Metall eine freiliegende größere Oberfläche zu schaffen, die Elektroden aus durchlöcherten Platten oder Blechen, eventuell zu mehreren zusammengelegt, hergestellt hat, werden gemäß vorliegender Erfindung die Elektroden aus gegittertem Blech in der Form des sogenannten Streckmetalls gebildet.While one has hitherto been exposed for the purpose with relatively little metal to create a larger surface, the electrodes from perforated plates or sheets, possibly merged into several, produced, are according to the present invention the electrodes are made of latticed sheet metal in the form of so-called expanded metal.
Dieses Streckmetall entsteht bekanntlich durch Schlitzen eines Vollblechs, welches danach in der Querrichtung ausgedehnt oder ausgestreckt wird, wobei sich die Schlitze zuAs is well known, this expanded metal is produced by slitting a solid sheet, which is then in the transverse direction is expanded or stretched, with the slits closing
klaffenden Öffnungen erweitern und die Zwischenschlitzstege eine eigentümliche Verschränkung ohne Querschnittsänderung erleiden. Verglichen mit dem durch Lochausstanzen aus gewöhnlichem Blech erhaltenen Material haben die Streckmetallelektroden einesteils den Vorzug billigerer Herstellungsweise, indem jeder nutzlose Abfall an Metall vermieden \vird, und anderenteils sind sie im Gebrauch wirksamer wegen der vorteilhaften Darbietung einer vergrößerten, in eigenartiger welliger Netzstruktur freiliegenden Oberfläche.Expand the gaping openings and the intermediate slit webs suffer a peculiar entanglement without any change in cross-section. Compared with that made by punching holes Material obtained from ordinary sheet metal, on the one hand, have the advantage of expanded metal electrodes cheaper production by avoiding any useless waste of metal, and on the other hand, they are more effective in use because of the advantageous performance an enlarged surface exposed in a peculiar wavy network structure.

Außerden werden , was der Wiederladefähigkeit derartiger Elemente zugute kommt, in den Gitterwerkzellen geeignete Aufspeicherungsräume für die wirksame Masse bzw. das elektrolytisch gelöste Zink geschaffen. Die verschränkten Stege gewähren auch einer daran angebrachten Füllmasse einen Halt.! the same one only with the edges on the inside or outside of the covering layer (fabric, Excitation mass, etc.) b..incoming change, so that a uniform attack on all sides of the zinc is made possible. Also be In the latticework cells, which benefits the reloading ability of such elements suitable storage spaces for the effective mass or the electrolytically dissolved zinc created. The crossed Bars also provide a hold to a filling compound attached to them.

Das Streckmetall kann mehrschichtig aufeinandergelegt eine einheitliche Elektrode bilden. Es kann aber auch in Verbindung mit Vollblech (vorzugsweise als Hinterlegungsschicht) angewendet werden, wobei eine besonders große Elektrodenoberfläche dargeboten wird.The expanded metal can be laid on top of one another in several layers to form a uniform electrode form. However, it can also be used in conjunction with solid sheet metal (preferably as a backing layer), with one particularly large electrode surface is presented.
Die Leitfähigkeit derartiger Streckmetallelektroden ist durch die Gitterwerkstege bis nahe zur Aufbrauchgrenze des Metalls wegen der gleichmäßigen Abnutzung gewährleistet. Überdies behält die Elektrode eine verhältnismäßig große Festigkeit und Steifigkeit, wodurch dem vorzeitigen Zerfall vorgebeugt wird.The conductivity of such expanded metal electrodes is up to through the lattice webs close to the consumption limit of the metal guaranteed because of the even wear. In addition, the electrode retains a relatively large strength and rigidity, whereby premature decay is prevented.
