I would like to know which emerging material has a huge potential to overtake the existing chemistries of Lithium Ion Batteries or which other technology can be an alternative for LIB.
I've watched the nanoflowcell stuff for a few years now, and it seems like a lot of money went into marketing, and their press releases read as much. At the same time, very little is said about science. So so far, it looks like all flair and little substance. The capacity and performance values seem through the roof, which is causing some doubts. That said, I am really interested how that will play out.
But if you are interested in RFBs, there are 3 main technologies: all-V, with many companies and groups doing that (UET, PVH, RedT, Storen, etc.), Zn-Br (RedFlow, Primus), and all-Fe (ESS). On the last one, these is some interesting research being done at Case Western U. There is also attempts of using LIBs chemsty in a flow battery format. One grout at MIT did that, naming electrolyte "Cambridge crude", and even funded a startup 24M, but since then the company abandoned flow architecture and are making regular (but improved) LIBs. Still and interesting concept. So lots of interesting stuff.
