Very cool tech, but I expect you're all looking for the cold water:

"Nevertheless, practical applications require far more aggressive optimizations with the large-scale continuous fabrication of CNFs, tuning its surface porosity, and finally additives in the electrolyte to stabilize the system to achieve commercial-grade performance."

CNFs and CNTs are fucking expensive and difficult to acquire in bulk. A lot of exciting climate/energy techs require them, I hope somebody starts pumping them out at scale soon.

"Stabilization of gamma sulfur at room temperature to enable the use of carbonate electrolyte in Li-S batteries" https://www.nature.com/articles/s42004-022-00626-2

after reading that it is pretty clear that the discovery wasn't accidental, but the really annoying thing is the exposition and exaggeration present in the text. "they were so surprised they had to recheck 100 times".

just state the facts. facts only! no embellishments, no color, no enthusiasm, please. I distrust authors who do this, because they are more interested in getting readers than they are telling the story.

    The researchers were trying to produce electrodes that reduced polysylulfide formation. That doesn't mean they expected a sulfur phase that was thought to only exist above 95C to be stable at room temperature.

    Extraordinary claims require extraordinary evidence.

    I think it's a publication that advocates for "green" energy - most of the other articles on the same subject have a similar optimistic + hypey tone.

Has a chance to revolutionize how we power our world.
