Reply to comment by Bridgebrain in Scientists lower price of lithium's best competition - flow batteries - by 20%. Makes the battery effectively equal to or cheaper than lithium ion when spread over 30 years (flow battery lifetimes are effectively infinite with light repowering efforts). by PorkyPigDid911

I looked up this type of battery, they are very slow to recharge. If anything they would supplement/complement existing battery/power solutions.

Right, iron-air are designed for multi day grid storage. For example, when it's cloudy for a week, these batteries discharge previous excess solar back into the grid. More about Form Energy's batteries if that's what you were thinking of.

Yep, but that's the exact stuff we need. We've got a few awesome options for cars and devices coming up. With graphene finally leaving the lab, salt batteries coming ever closer, and a few solid state options on the horizon, the problem always comes down to "scalability", and these provide a high scale focused solution
