They don't detail the composition of the electrolyte, how it's produced, how it's consumed, and what by-products are emitted after, let alone what the cost might be.

It's nice.

No cynicism needed.

I imagine you were aware that I was referring to announcements of new battery (and Fuel cell) tech, especially those involving major breakthroughs in performance or cost.

Okay, but this is the "Future" battery tech thread. A few decades back we would all be driving BEVs soon because of soon to appear improved batteries, and we've seen how that worked out.

The present and the past was once the future. And some futures are still in the past, and may always be.

Not a lot of technical details. What it got my attention is the high temp operation. Nssan should be interested. And the 30000 cycles with no degradation.

Yes, but this part sounds too much like Nissan's battery testing procedure: " “We show that we can operate this material at high temperature for 24 hours straight over more than 30,000 cycles and it shows no degradation,” Wang says."

The bigger test is how well does it do for YEARS at higher temperatures. Dahl's presentation talked about how all the older tests were just basically "beating the clock" when it came to rapid high temperature charges/discharges.
BTW, what is gas2.org? They don't seem too happy that Elon is "fleecing the rich" with the P100D, so he can build the Model 3. Elon has never made any secret of that fact, it was in Part 1 of his public plan. I wonder if the guy also hates Ferrari, Lambo, Maclaren, etal for fleecing the rich? :? A $140,000 5-passenger premium sedan that can beat a $1 million sports car 0-60? Sounds like a bargain. :lol:
