[0019] (1) Preparation of plating solution:

[0020] a. ZnCl 2 、H 3 BO 3 、BiCl 3 , Pb(AC) 2 and sodium citrate dihydrate were dissolved in distilled water to prepare solutions, in which ZnCl 2 Solution concentration is 135 g / L, H 3 BO 3 Solution concentration is 25 g / L, BiCl 3 The solution concentration is 0.05 g / L, Pb(AC) 2 The concentration of the solution is 0.06 g / liter, and the concentration of the sodium citrate dihydrate solution is 0.05 g / liter.

[0021] b. La 2 o 3 The white powder is dissolved in acetic acid with a concentration of 36% by mass percentage to prepare a concentration of 0.2 g / L containing La 3+ solution.

[0022] c. the ZnCl prepared in step (1) step a 2 solution and BiCl 3 The solution is mixed evenly, and it is observed that a white precipitate is produced, and it is fully stirred, and then poured into the mixed solution into the Pb(AC) prepared in the first step a of step (1). 2 solution, fully stirred until the solution becomes clear;...

Abstract

The invention discloses a method for preparing Zn-Pb-Bi-La alloy electrode material through pulse electrodeposition. The method comprises the following steps of: (1) preparing a plating solution as required by using ZnCl2, H3BO3, BiCl3, Pb(AC)2, trisodium citrate dehydrate, La2O3 and acetic acid with the mass percent concentration of 36%; (2) pre-treating a copper matrix: sanding, distilling and washing, conducting alkaline degreasing, distilling and washing, conducting ultrasound degreasing, and distilling and washing; and (3) putting the pre-treated copper matrix and a pure Zn plate into the plating solution for plating. According to the method disclosed by the invention, the operation is simple and convenient, the operation and the control are easy, the plating solution is stable, the deterioration is not easy, and the prepared Zn-Pb-Bi-La alloy can be used as the zinc electrode material with good technical parameters, so that the method disclosed by the invention has good application prospect.

Description

Technical field [0001] The present invention involves the field of pulse deposition technology, and specially involves the method of pulse deposition systems of ZN-PB-BI-LA alloy electrode materials. Background technique [0002] Zinc electrode has high energy and ratio, and zinc has the advantages of rich resources, low cost, non -toxicity, etc. Therefore, zinc electrodes can be combined with many materials into alkaline chemical power supply, which is widely used in aviation, military, energy and energy, andOther areas; but because zinc electrodes will occur during the charging and discharge cycle, zinc "deformation", zinc branches, corrosion and passivation will occur, resulting in low cycle life of zinc battery, which largely limits the application of zinc batteries. [0003] In the past, mercury or mercury chloride was often mixed in zinc electrodes to form mercury and zinc, which increased the hydrogen analysis of the zinc electrode, slowing the corrosion of zinc electrode....
