It sounds like it works really well. The physical size does sound quite large, but I'm not sure how that compares against other types of batteries.
It probably doesn't matter. This type of battery is not all that interesting for things like electric cars, rather more so for things like grid energy storage on a massive scale. Think 1000s of these in a large building, getting charged during the day with excess solar energy, releasing it into the grid at night. Stuff like this is what has been missing to make even better use of renewables.
How about one of those in your basement or shack to charge your car overnight?
well its usually not in your basement, but should be outside in a home sized battery cage (similar to those used in parking lots to charge EVs). in a more ideal time period, itll just be another external installment like outdoor AC units. to get there, home energy storage has to get cheap enough so that people installing solar at home also opt for energy storage.
one of the big problems EV have is most charge at home at night when peak usage is at instead of the most opportune time, which is when the sun is up during working hours. Its why theres a movement to install charging stations at workplace buildings as a benefit to workers (no longer pay for "gas"). If the average home user had a battery wall, then you can just circumvent that problem alltogether.
