Given the amount of published enthusiasm about redox flow batteries, you'd think we'd all be driving vanadium battery electric cars by now. Instead, despite promises of commercialization, I encounter nothing but phone numbers and e-mails that go unanswered. The relevant businesses seem to producing 'vaporware' instead of real cells.
Anybody got specs for that iron redox cell ( Trunov)? I'm tempted to build one for myself. It's incredible that such a powerful technology stands unused as yet.
