For analysis AA batteryIt will require some ingenuity and care. In fact, opening a galvanic cell unless absolutely necessary is a bad idea. You never know what might happen during disassembly. For example, chemicals can come into contact with your skin and damage its integrity. More often than not, your hands get dirty with coal dust, making it difficult to wash off. This can leave you feeling dry and sometimes burning.
Step-by-step instructions for disassembling an AA battery
We'll be disassembling a battery whose voltage fluctuates around 1 V. It was in a Chinese alarm clock, but it no longer worked on it.
Step #1.
For safety, wear gloves and, preferably, safety glasses. This will help prevent battery contents from coming into contact with your skin and mucous membranes.
Step #2.
The first step is to remove the plastic film. This can be done with any sharp instrument, such as a knife, scissors, needle, awl, or screwdriver. In some cases, regular fingernails work well.
Once the sticker is removed, a zinc or aluminum cup appears. Some batteries may have a paper cylinder. The only accessible place for this battery to disassemble is the negative terminal.
Step #3.
Very carefully straighten the curved edges at one end of the battery. You can use a regular screwdriver and pliers for this.
Step #4.
Now we take out the negative contact by prying it up with scissors, for example.
Step #5.
Now we'll pick out everything inside the cup. Before disassembling it, we assumed this battery would contain a standard graphite rod. But it turns out this battery is manufactured using some special technology. The rod was a thick, whitish paste with a metal needle inserted into it.
In the end, there was nothing special about this battery. The only thing that could be saved for further use was the metal cylinder.
What happens if you disassemble the battery?
Many people wonder what happens if they open a zinc cup. In reality, nothing terrible will happen. Let's say you take apart a half-discharged battery. You'll end up with a bunch of debris, maybe a little gas, and nothing more. You might contaminate your skin, and that's it.
Inside you will see coal, graphite rod and in some cases a little acid.
