Reply to comment by astrangeparrot in A breakthrough in electric vehicle battery design has enabled a 10-minute charge time for a typical EV battery. The record-breaking combination of a shorter charge time and more energy acquired for longer travel range was announced today by Wagamaga

I think what they are saying is that this specific system would be used on a vehicle with a smaller battery so the heat would be less of a factor. Maybe something like a delivery vehicle that makes short trips and might sit often. If you never intend on taking the vehicle on a long trip then the larger battery wouldn't be necessary and an unneeded cost.

This. Plus batteries are heavy. Less mass is always better.
