I don’t know enough chemistry to evaluate this design at all, but I know him to be humble and careful enough that he wouldn’t be proposing this if he hadn’t done his homework.

Can somebody who knows this stuff please give him some substantive feedback?

In general the standard response to new battery tech is that there's a ton of stuff that works great in the lab but getting to production is 10x harder. See Elon's first quote here for instance:https://electrek.co/2017/08/03/elon-musk-hints-at-new-battery-breakthrough-on-the-horizon/ …

It's an aggressive quote, and I really don't want to poohpooh someone's honest work. So maybe a better way to put it is that they should be aware of these effects, and if so, godspeed.

I’ll need to pull out some references tomorrow, but here are a few qualitative comments coming to mind: 1. What is the theoretical gravimetric and volumetric energy density? It should be >1.5x LiB to get interest. 2. Am I correctly calculating potential at 2.1V? If so, it’s...

...low compared to LiB. 3. What is the relative size of NaTTFMB compared to LiPF6? Bulky ions have slower diffusivities, reducing specific power. 4. What is the stability window of DTBE? Does the HOMO/LUMO gap of DTBE mesh with this system? Why not traditional EC?pic.twitter.com/2LHR2eGxy9
