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)

multiple times the big one was to wrap a spoon in duct tape and microwave it or boil bleach and drip alcohol in it to make crystals.

I thought it was ammonia instead of alcohol.

Sure. But we need to see pics, or it didn't happen.

The abstract doesn't mention them re-gaining their old capacity. It only says they shrink. And something about voltage. So I have my doubts. I mean it's nice if my spicy pillow shrinks a bit. But what does that help if it continues to stay nearly dead? And an application in products would be hard to accomplish. At that temperature, all the plastic etc is going to melt. Maybe the solder as well.

Yes. If you aren't reading any battery tech article with a huge amount of skepticism you are doing it wrong. More than any other tech sector I can think of, battery research is just absolutely plagued with low quality research that consistently gets picked up by media outlets.
