Question Can someone explains me the science behind reviving the laptop battery freezer method?

I just recently watch this video:

And i wonder how does putting the battery in freezer would make it come back to life?

Don't believe everything you see on utube.

It may 'come back to life' for a short while.
Using it, it will still be long down the road to dead.

That is absolutely not a permanent fix.

Also, you NEED to be cognizant of the actual battery type.

NiCD or NiMH, fine for a short term bump
Lithium, absolutely not.

You might want to stay away from videos like that that preach snake oil being the end all be all solution. There's no science behind it and you're introducing a battery into a freezer...? Clearly it's a crap video uploaded to garner some attention(since bad publicity is still publicity and YT thrives on engagements). In fact, the video production looks like it was put together with content cropped/snipped from other people's content.

As state above by my colleague, there's nothing to it. If your laptop's battery is being funky, replace it with a genuine part not the one's found off of Aliexpress with half hearted info slapped across them.

Ok so it will come back to life for a short while, but how?
I just want to know the science behind it, im not trying to fix it.
just curious you know.

I do not know the specific chemistry involved.

Apparently, it slows down the movement of the li ions.

However...Lithium batteries and moisture do NOT go well together.
You could easily explode the batteries inside your fridge, due to the accumulated condensation.
