Description

Background
With the development of science and technology, the field of electrochemistry is also developed vigorously, and the research on novel electrode materials is particularly important in the current scientific research of hydrogen production by electrolysis and organic wastewater electrolysis, the electrode materials are often subjected to an electrodeposition technology in the preparation process, and the prepared electrode is also subjected to performance test, wherein the performance test comprises a very important electrolysis experiment. However, in these two important processes, the distance between the two electrodes, the depth of the intercalation solution and whether the two electrodes are parallel to each other greatly affect the experimental results, such as the current efficiency, the improper electrode distance and the depth of the intercalation solution may cause the current efficiency to be reduced and the energy consumption to be increased, such as the improper electrode distance and the depth of the intercalation solution may cause the prepared electrode to be unsatisfactory or even fail to be prepared, such as the improper electrode distance and the depth of the intercalation solution may cause the tested electrode performance to be inaccurate … ….
The majority of the related art currently stays on the electrode fixing without considering both the electrode pitch and the depth of the intercalation solution (the depth of the intercalation solution of the electrode is actually the height of the adjustment electrode, and is therefore replaced by the height hereinafter). Document 1([1] chenjuan. an electrochemical workstation electrode fixing device [ P ]. chinese utility model patent: CN201620185080.7,2016-09-07.) discloses a novel electrode fixing device: the upper end of the U-shaped base is fixedly provided with 4 same cross rods, the cross rods penetrate through four corners of 4 square pieces with coincident central lines, the middle two square pieces are fixed square pieces, the two sides of the middle square pieces are movable square pieces with screw rods, the screw rods penetrate through the side wall of the U-shaped base and are matched with the opening threads of the side wall, and therefore clamping of the electrodes can be achieved by rotating the two screw rods. The device can well clamp the electrodes to play a role in fixing and ensure the constant distance, but the device cannot realize the flexible and accurate adjustment of the electrode distance and height. Document 2([2] tangclent, yangbuwei, guoshi. an electrode holder and locator [ P ]. chinese utility model patent CN202020013376.7,2020-09-11.) discloses a novel electrode holder: two clamping pieces which are vertical to the axial direction of the fixed rod are arranged on the fixed rod, and the distance between the clamping pieces can be adjusted in a sliding mode. The device can clamp the array electrodes, has high universality, and cannot accurately and quantitatively adjust the electrode spacing and the height of the electrodes although the electrode spacing is adjustable.
