Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a cross-sectional view of an electrode for electrolysis according to an embodiment of the present invention, and shows a case where it is used as an anode of an electrolytic cell.

[0023] like figure 1 As shown, the electrode 1 for electrolysis is formed in a cross-sectional arc shape, and in this embodiment, the two electrodes 1 and 1 for electrolysis are arranged in a semicircular shape, which also serves as the cell wall of the electrolytic cell 2 . On the inner surface side of the electrodes 1, 1 for electrolysis, the drum-shaped cathode 4 is provided at intervals so as to stabilize the gap in the circumferential direction. In the electrolytic cell 2, the electrolytic solution L can be supplied through the liquid supply part 2a provided between the adjacent two electrolytic electrodes 1, 1, and the supplied electrolytic solution L is transferred fro...

Abstract

Provided is an electrolytic electrode used as an anode arranged at a distance from a rotatable cathode.  The electrolytic electrode includes a base (10) having an arc-shaped cross section and a plurality of electrode plates (12) arranged on the inner surface of the base (10).  The electrolytic electrode is configured so that power can be supplied separately to each of the electrode plates (12).  With this configuration, the electrolytic electrode can easily obtain a uniform electrolytic current density.

Description

technical field [0001] The present invention relates to an electrode for electrolysis, and more specifically, relates to an electrode for electrolysis used for producing metal foil such as electrolytic copper foil by an electroplating method. Background technique [0002] In the production of metal foil by electroplating, in recent years, electrolysis equipment tends to increase in current and size, and is used as an electrode for electrolysis of an insoluble anode, and a curved electrode that can save space is known. For example, in Patent Document 1, it is disclosed that the anode plate is installed and bent on the casing by bolts to form an arc-shaped structure, and the arc-shaped anode is arranged at intervals around a freely rotatable cylindrical cathode. The plates, through the presence of an electrolyte in between, are able to deposit metal foil on the surface of the cathode. In addition, the distance between the anode plate and the cathode can be adjusted by interpo...
