It's highly unlikely that they solve what is essentially a heat distribution problem with new battery materials. If you stick a huge number of cells in a giant cooling system then you can charge even lithium considerably faster than we do now for all of the 100%.

We are limited by the space, how good the battery pre condition charging is,maintenance schedule of the car and charging point.

My car has a separate fluid cooling system for ultra rapid charging that has its own maintenance schedule, if this system was bigger and didn't have to go a minimum of 12 months between changes then it could be charged for longer at higher speeds.

If my car had a bigger battery with more cells in a suitable arrangement then again I could charge faster for longer as the charge is spread out across the battery. However eventually you'll hit the point that you are only charging a few of the cells as the rest are full and you have to slow down or the battery will get too hot.

I just don't see them completely solving the heat problem, just improving the current percentages.
