Technically, yes. Most of the time. Beyond that, no. It isn't good enough for a great deal of people. Lithium batteries are hard to recycle, hard and expensive as hell to replace, give constantly diminishing returns as range goes down every year it's owned, people in apartments can't charge them without going to charge stations that are more expensive than gasoline, and range anxiety is very much a thing that prevents anyone from exclusively owning electric vehicles.
Transportable fluid that holds more density than lithium (which means vehicles won't be so heavy which saves on a lot of issues) and doesn't require a nationwide restructuring of the electrical grid system seems like a way better idea than adding an extra 1200 pounds of battery that will cost $12,000 to replace when it goes bad.
I only wonder if the liquid can be safely disposed of or recycled/sustained. Regardless, setting up a system to use this would take two decades to really implement and we should have solid state batteries before then that should get rid of quite a few of the several shortcomings of lithium batteries.
