It depends how much power they can dump in 1 second. If more or the same as lion tech stacks then they will be viable for EVs.
Another thing. Fast charging stationary power might be important for a distributed power grid. Currently one of the problems in some implementations is that excess power from clients cant even be accepted. Fast charging storage might be important for accepting large excess coming in from the grid.
Tooo tooo, rooo tooo tooooo.
