This article says that the iron batteries cost is as low as $76.11 per kWh, but lithium ion prices are $108 per kWh right now. I have no idea how they got to 80x cheaper in that headline
Edit: I think they're just saying that the cost of raw iron is 80x cheaper than the cost of raw lithium by weight. That's really deceptive
Are they including the price over time if they last significantly longer than the lithium batteries?
16 years, that's similar to the expected lifetime of lithium solar batteries.
Yeah not a very good description then
