Applying 'extreme heat' to lithium-ion batteries reportedly restores their capacity, and I think it's the sustainable tech breakthrough of 2025 (www.techradar.com)

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.
