- DavidPiper 1y agoThere was a company in Australia called Redflow making these too. They were liquidated end of last year. Much as a like the idea of niche and diversified battery technologies, it seems like there isn't enough motivation to move too far away from Lithium-based solutions (no pun intended).
- dzhiurgis 1y agoI don't get the pun. Is it chemistry related?
- etrautmann 1y agoThe double meaning of solution
- dzhiurgis 1y agoAhh. I thought lithium is one that's most likely to give away its electrons or something like that.
- DavidPiper 1y agoLooking back, I also didn't even notice the "liquidated". Must be tired today.
- jeffbee 1y agoVanadium flow batteries are better in the economics.
