I keep being intrigued by vanadium redox flow batteries, and I've seen some in the real world in stationary applications. And the prospect of instant charging by spit-swapping in a mobile application is pretty wild.
How scarce is vanadium, though?
- selectodude 7y agoIt’s like 2 percent by mass of spent iron slag.

- marcosdumay 7y agoVanadium has an horrible weigh/charge ratio. That's why it's used in stationary applications. Sodium redox flow batteries are all the hype nowadays, because sodium is much cheaper, sulfur for the oxydizer is also very cheap, weight/charge is very high, and volume/charge (important for stationary applications) is also much higher. But I think it's stuck in a patent minefield.
