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.
