Yes flow battery tech looks interesting, although has been around for a while, such as Vanadium Redox batteries by UK startup RedTen, amongst others, for static storage from renewables.
At the moment I believe the energy density is nowhere near what we'd need for vehicles, but it's good to see developments in this direction.

Done some quick research, the simple explanation is you are pouring in a fully charged battery, the discharged battery fluid is removed and can be used again once charged up.

Flow batteries are heavy. Have interesting possibilities for static storage - such as connected to the grid to balance demand with renewables, but as far as I know no one has come up with anything close to what a car would require in terms of energy density.
