No result when attempting to repaire battery in freezer

I read on a forum, it is possible to repaire a battery when you freeze it in the freezer.
I packed the battery in a plastic bag (zip-lock) and I put the battery in the freezer for 24 hours.
The temperature in the freezer is -18ºC.
After 24 hours I took out the battery from the freezer, I unpacked it from the plastic bag, and cleaned it.

I inserted the battery into my computer and charged it for 8 hours.
After 8 hours of charging, my battery still worked for 20 minutes as before.

The myth to repaire a battery in a freezer is not possible.
It does not work for me.
