My buddy @peroxycarbonate has an idea for a battery design that should be cheaper and more energy efficient than lithium-ion batteries & could make electric cars competitive. http://www.bhauth.com/files/fbd5da5a/tech%20catalog.html …
Can somebody who knows this stuff please give him some substantive feedback? @perrymetzger @DanielleFong

I have a chemistry background but I know O(0) about practical battery design.

(I mean, I've read a lot of papers about it, but that qualifies me for nothing other than to be able to parrot some things that people who actually understand it have said. I really have no basis for an opinion on this design.)

Is it really better than SOTA? Compare: > ~400Wh/kg based on active materials, realistically corresponding to ~240Wh/kg for a commercial product vs: > the batteries that Tesla uses in its Model 3 — the so-called 2170 cells — are an estimated 250 Wh/kghttps://www.theverge.com/2019/4/4/18293989/innolith-ev-battery-breakthrough-lithium-ion …

One figure of merit not discussed much is amortized cost per Wh (or kWh) of storage over the battery's lifetime. Fixed installations care more about that since weight is irrelevant. For that, Lithium based batteries are often not optimal.
