Abstract

The zinc-selenium-antimony electroplating solution contains seleninic acid, a buffering agent, a complexing agent and a proper amount of water, and further contains zinc salt and antimony salt, and the electroplating solution comprises the following components: 0.2-0.8 g / L of seleninic acid, 2-8 g / L of buffering agent, 0.5-5 g / L of complexing agent, 0.5-4 g / L of antimony salt and 0.2-1.5 g / L of zinc salt. Compared with the prior art, the zinc-selenium-antimony electroplating liquid and the preparation method thereof have the beneficial effects that a uniform zinc-selenium-antimony plating layer is obtained through the electroplating method, the color is attractive, the specific capacity is high, and the stability of the electroplating liquid is good. The electroplating liquid with the proportion has a stable polarization curve, and can be matched with simple operation to obtain a product with good and uniform performance repeatability.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a zinc-selenium-antimony electroplating solution and a preparation method thereof. Background technique [0002] Electroplating has the advantages of low cost, simple process and easy operation, and is widely used in life. Electroplating single metal is far from meeting the modern demand for functional materials. Therefore, electroplating multi-component alloys have developed rapidly in recent years, with a wide variety of materials and excellent material properties, and have been widely used in the magnetic industry and energy fields. [0003] The theoretical lithium / sodium storage capacity of antimony is as high as 660mAh / g, which is much higher than the current commercial carbon materials. At present, the methods for preparing zinc-seleno-antimony alloys mainly include hydrothermal method, cross-linking reaction method, etc., and these preparation methods have disadva...
