> A 10x speedup of charging?

Not possible with existing infrastructure. The limiting factors are cooling the batteries and feeding them enough power. On small scale like laptops it's possible to speed up charging but not at large scale like cars.

That isn't to say it may be possible in the future but it isn't now.

It increases the charging speed by reducing the heat produced while charging.

If it makes charging more efficient (less energy converted to heat, more stored) then it would improve the charge rate but not by 10x.

Charging rate is typically limited by thermals. If you drop heat by 10x you can bump charge speed by the same.

The main way you can make batteries charge faster is my reducing the heat produced. This is the first limitation you hit anyway
