Destructive ideas welcome (YT Video in OP!)

I have a new Samsung 30Q that has a self discharge problem. I put it on the shelf fully charged a year or more ago, and found it flat 0.0 volts. It’s not a lot of self discharge, I tested it at about 0.1 to 0.2 volts per hour. So I can charge it up for one last farewell party.

Any ideas on what might be fun? I can share the results.

And yes I know this is dangerous, I have proper safety gear. And will charge it outdoors.

hi, if you’re storing cells its not a good idea to fully charge them, around 3.5-3.6V would be better.

As for the farewell party. maybe shoot it with an air rifle, or short circuit it.

Yea I know about best storage voltage. But life happened.

Well this is America, so my rifle isn’t an air rifle Silly That could be fun. And being at a safe distance would be easy.

Observing all laws and appropriate safety precautions, I think I’d like to see it discharge EXTREMELY rapidly.

Full 8AWG short.

Measure current draw with a clamp meter.

I like that idea a lot, but I don’t have a clamp meter.

Cu is sooo last year. Make your own superconductor. Liquid nitrogen not included; and it won’t superconduct very long as it heats up!

He’s joking, the best marksman would spend all day trying to hit that at 1000yards with consumer grade guns and ammo. And still never hit it.

Ooh, ooh. 12ga shotgun shell (~18mm), cut down to remove the shot but leave the wadding, drop the 18650 in there musket-style, and blast it into a brick wall.

18650… that’s a little loose for a 12 gauge and a bit tight for a 16 gauge… but I bet it would fit nicely in a in a high-brass 3” 12g birdshot shot cup.

Just Saying….. Beer

Or, maybe you have a pair of large jaw vice grips or channel locks that need heat treated?

Hence “leave the wadding”. Let that do all the work. LOL

That shotgun idea could be impressive.

Or it’s possible the sidewalls of the battery will buckle due to the high acceleration involved, jamming the battery inside the barrel, likely damaging the barrel and potentially even creating a risk of overpressure.

I wouldn’t recommend it without taking significant precautions.

Yea, that’s what I was thinking. I can’t guarantee my safety doing that, so that idea is out.

If the cell fits in the shotcup, and the barrel is not choked, it will be safe.

Well I see two possible outcomes, a screwed up gun and/or personal injury… or it fires like a normal projectile and is boring.

Why is that? It’s perfectly legal, as far as the ATF is concerned. Steve

@JoshK, since I’m the kind of person that likes to be friendly to my surroundings and the general environment, here’s what I would do:

1. Discharge the cell to 0V.

2. Go outside with a bucket of water.

3. Wear two pairs of medical gloves, and a full laboratory suit.

4. Open the 18650 by removing the top cap with a dremel.

5. Proceed with the disassembly of the cell, by first putting the steel casing in the water to clean it, and then doing the rest WITH GLOVES ON. DO NOT TOUCH YOUR FACE IN, and wear a respirator if possible.

Yes, but make sure to put the casing in water so that the electrolyte(comprised of HF and other solvents) gets converted into a safer form.

So yeah, just don’t open the cell up without gloves.

Some things I discovered:

1. The cell casing and anode can easily be recycled. The casing can be melted, while the anode can be rather easily separated into graphite and copper. The cathode is another story.

2. There’s quite a bit of copper inside of a cell. With thousands of cells, this could actually get rather profitable if you were to actually recycle it.

3. If you could actually weld them shut, you could make conductive spacers. Smile

I think this is the best answer so far. You could probably add threading for a twisty head and use the body as a AA or AAA battery carrier. I’d be partial to putting the emitted inside a small hole on the negative end and using the positive contact as a clicky switch. A LOT more work, but it will still kind’a look like an 18650.
