Sounds like a horrible idea if not carefully controlled. Perhaps up to 80 degrees in an oil bath could redissolve some of the electrolytes. I guess it could work. Anything above 100 is asking for trouble.
no, it’s an organic solvent like ethylene carbonate/propylene carbonate + some other stuff, which have a boiling point of 230+°C ( 446°F)
heating up batteries is (mostly) fine (under controlled scenarios with known good batteries, spicy pillows can always happen with bad batches) as long as the plastic holding them together doesn’t melt
you physically CANNOT make a lithium ion battery with water because lithium reacts with water
from the wikipedia page
Lithium reacts vigorously with water to form lithium hydroxide (LiOH) and hydrogen gas. Thus, a non-aqueous electrolyte is typically used, and a sealed container rigidly excludes moisture from the battery pack. The non-aqueous electrolyte is typically a mixture of organic carbonates such as ethylene carbonate and propylene carbonate containing complexes of lithium ions.[45] Ethylene carbonate is essential for making solid electrolyte interphase on the carbon anode,[46] but since it is solid at room temperature, a liquid solvent (such as propylene carbonate or diethyl carbonate) is added.

So you’re saying I SHOULDN’T preheat my toaster oven to 425F???
UH-OH!!!
brb. Gotta put out some fires.
How is the boiling point of water relevant to something that’s made of plastic and metal?
Well the electrolyte solution is water based so exceeding the boiling point will cause pressure buildup inside.
Edit: hmm seems I’m saying nonsense. The solvent may be able to handle higher temperatures.
wha wha what

That still doesn’t follow. For every mole of particles dissolved in a liter of water, the boiling point of water increases by about 0.5°C.
Good point. It’s highly concentrated inside a battery if not saturated. Hmm. I still wouldn’t expose them to such high temperatures.
Perhaps a longer duration at lower temperature is safer. I might try it some day with some waste batteries and a battery tester.
