Preparation method for preparing carbon fiber composite electrolytic electrode, and electrolytic electrode

Abstract

The invention provides a preparation method for preparing a carbon fiber compound electrolysis electrode. The preparation method comprises the following steps that S1, two carbon fiber strips are superposed up and down and are mutually perpendicular; the carbon fiber strip located above serves as a first carbon fiber strip, and the carbon fiber strip located below serves as a second carbon fiber strip; and the first carbon fiber strip and the second carbon fiber strip are in straightly stretched states and are tightly contacted; S2, the second carbon fiber strip is folded towards the directionwhere the first carbon fiber strip is located; and after the second carbon fiber strip is folded, the second carbon fiber strip clamps the first carbon fiber strip; S3, the first carbon fiber strip is folded towards the direction where the second carbon fiber strip is located; and after the first carbon fiber strip is folded, the first carbon fiber strip clamps the second carbon fiber strip; S4,the S2 and the S3 are sequentially repeated until the carbon fiber strips can not be folded, and a semi-finished product of the electrolysis electrode is obtained; and S5, the semi-finished product issubjected to heat treatment and pressure treatment, and the electrolysis electrode is obtained. The invention further provides the carbon fiber compound electrolysis electrode prepared by the preparation method.

Description

technical field

[0001] The invention relates to a preparation method for preparing a carbon fiber composite electrolytic electrode and the corresponding electrolytic electrode. Background technique

[0002] In the electrolysis process, the electrode is the most important part, and its quality is directly related to the efficiency of electrolysis and the properties of the electrolysis product; except for some anode metal electrodes that will dissolve during the electrolysis process, most electrodes do not participate in the electrolysis reaction. There is no change before and after electrolysis.

[0003] Currently commonly used electrode materials include noble metals (such as platinum, titanium), rare metals (such as palladium, technetium, ruthenium) and graphite; the above-mentioned electrodes all have certain defects: noble metals and rare metals are expensive, and the hardness is not high; graphite toughness is not enough , the texture is brittle and easy to break.
