Iron flow batteries are already in commercial use. For example: https://essinc.com https://essinc.com
The 'cells' cost practically nothing to manufacture and utilize a membrane already common in lithium ion battery manufacturing, and there's nothing dangerous or toxic in the battery system. It's iron (in various oxidation states), salt, and water.
It's been a while since I looked at the whitepapers (which they've since pulled) but I think the secret sauce was how they managed the electrolyte's pH level.

- Ballas 5y agoWhat is the energy density of these batteries? Last time I checked, it was infeasible to replicate something like a powerwall in even 10x the volume. Which means it is a non-starter for EV.
