Technical Field
The invention relates to the technical field of electroplating alloys, in particular to an electroplating indium alloy for preventing gas expansion of a mercury-free zinc-manganese alkaline battery.
Background
In the prior alkaline zinc-manganese cell battery, the raw material of zinc is hidden in the negative electrode, so mercury must be added to prevent the zinc from generating gas and expanding when contacting with other raw materials or metals. Meanwhile, since the battery contains mercury, which is difficult to degrade, the discarded battery inevitably causes serious pollution to the environment. The mercury-free implementation of such batteries has been carried out on a large scale, and as the technology advances, patents ZL01234722.1 ZL01129898.7, ZL200620123203.0, etc. have provided alternatives for this purpose. However, these solutions have significant drawbacks and do not meet the production and functional requirements of such batteries well.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the indium electroplating alloy which is safer, more reliable and low in cost and is used for preventing the gas expansion of the mercury-free zinc-manganese alkaline battery.
In order to realize the purpose, the technical scheme provided by the invention is as follows: the electroplated indium alloy at least comprises indium and one of zinc or tin, or both zinc and tin, wherein the indium is a basic metal of the electroplated indium alloy, and the zinc and tin are auxiliary metals of the electroplated indium alloy.
The metal content ratio of indium in the electroplated indium alloy is 10-95%, and the metal content ratio of zinc or tin or the total of the zinc and tin is 5-90%.
After the scheme is adopted, the invention has the greatest advantages that indium is used as basic metal, auxiliary metal is added, the invention aims to reduce the cost of pure indium electroplating and defects related to a pure indium coating, and special functional requirements of the battery industry are met.
Detailed Description
The present invention is further illustrated by the following examples.
The preferred embodiment of the invention at least comprises indium and one of zinc or tin, or both zinc and tin, wherein the indium is the basic metal of the electroplated indium alloy, and the zinc and tin are the auxiliary metals thereof. In addition, the invention can select various auxiliary metals according to different use occasions and functional requirements. Here, it can be said that indium is a skeleton and the other auxiliary metal is a filler.
a. The alloy metal content proportion in the electroplated layer is as follows:

b. Content of metal ions in the plating solution:
0.1-30 g/L indium
Auxiliary metal zinc or tin or zinc and tin total 0.01-30 g/L
0 to 15 g/L of auxiliary metal B
The auxiliary metal is necessary to remove zinc or tin or both zinc and tin, the addition of B is according to the needs, and in most cases, only indium and zinc or tin or zinc and tin are needed for convenient operation and simple control. Advantageously, it is added without harm at least, and not as an impurity due to impurities in the raw material.
2. The technological parameters are as follows:
the pH value of the electrolyte is more than 7

Pull plating for 10-1200 sec
An anode pure indium plate, an indium alloy plate containing auxiliary metal, a graphite plate, an insoluble stainless steel anode, a titanium anode plated with platinum or ruthenium iridium, and the like. Rack plating, barrel plating, continuous plating and pull plating.
3. Electrolyte components:
consists of metal salt, conductive salt, complexing agent, surfactant and brightener. The surfactant and brightener are not essential but may be added as needed. Both of these are of course advantageous in improving the quality of the plating.
All metal salts of indium, zinc, tin and other metal ions can be used, regardless of their solubility in water, and high or low forms of these metal ions can be used.
4.

d. Discharge gas generation (more than or equal to 1%) of mercury-free alkaline zinc-manganese dioxide battery
5. Construction object:
a. barrel plating and rack plating: and a mercury-free alkaline zinc-manganese battery cathode cover.
b. Continuous plating and pull plating: the negative plate of the mercury-free alkaline zinc-manganese battery is plated with indium alloy, then stamped into a negative cover, and then the battery is assembled.
c. No matter the negative electrode cover or the negative electrode piece of the mercury-free alkaline zinc-manganese battery, nickel, copper or other coating layers can be electroplated by a publicly known method before indium alloy electroplating, so that the purposes of rust prevention and brightness and improvement of the binding force of the indium alloy coating layer and a substrate are achieved, and the effects of liquid leakage prevention and air expansion prevention can also be achieved.
