This looks like it's going to be a winner - fast-charging and
long-range capacity:

What electric cars, trucks and boats lack now is long range capacity.
Max range tops out at a bit over 300 miles even for the best, and is
frequently a lot less. Recharge times are measured in large fractions
of an hour or more. This new battery technology could potentially
solve that, and the stock (QS) has been jumping.
