As someone who buys, sells, installs, and operates enormous volumes of battery assets, I disagree.

No one I know who is in battery tech for a living is writing off sulfur batteries as napkin-math-interesting only. I’m curious to know who you work with that believes otherwise in industry so assertively.

I've worked at a battery-analytics company which given your background you might have heard of, this involved hosting the Bay Area battery research community on a monthly basis. I'm not dismissing lithium sulfur as a viable technology. I'm saying that trying to calculate the environmental impact of a technology like that before it has sizable production and several rounds of process improvement is napkin-scribbling. Useful in some ways, but it's premature to draw conclusions from it. That's all.

Fair enough. Indeed my only point was that lithium-sulfur has production potential, as does solid-state, etc. and that’s where the industry interest originates.

[Animats]

Is anybody actually selling a lithium-sulfur battery? Even as a sample?

[herewego]

Who cares? It’s a technology in development intended to help solve an unsolved problem — efficient energy storage. This is research.
