Abstract

The invention relates to the technical field of electroplating, in particular to nickel-antimony electroplating liquid and a preparing method thereof. The electroplating liquid comprises boric acid, sodium hypophosphite, a complexing agent and a proper amount of water. The electroplating liquid further comprises nickel salt and antimony salt. The electroplating liquid comprises components including 20-80 g / L of the boric acid, 10-80 g / L of the sodium hypophosphite, 10-80 g / L of the complexing agent, 1-20 g / L of the nickel salt and 1-10 g / L of the antimony salt. A uniform nickel-antimony clad layer is obtained through the electroplating method, the color and luster are attractive, the specific capacity of the clad layer is high, and stability of the electroplating liquid is good.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a nickel-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 daily life. Electroplating single metal is far from meeting the modern demand for functional materials. Therefore, with the rapid development of electroplating multi-element alloys in recent years, there are various types and excellent material properties, and they have been widely used in the magnetic industry and energy fields. [0003] The theoretical capacity of antimony is as high as 660mAh / g, which is much higher than the current commercial carbon materials. Antimony and nickel-antimony alloys are a class of energy materials with very promising prospects. At present, the methods for preparing nickel-antimony alloys mainly include hydrothermal method and cros...
