Paper is linked at https://onlinelibrary.wiley.com/doi/10.1002/adma.201902518 / https://doi.org/10.1002/adma.201902518 , but is paywalled; only the supplementary info on construction is available. Does anyone with scihub access know what metric is being used for "seven times more efficient" - charge/discharge cycle efficiency? Power/weight?

The article says "a specific energy density that is more than seven times greater than commonly used lithium-ion batteries"

Aside, doi.org is redirecting to crack/malware site "thesoftin.com" both @1.1.1.1 and @8.8.8.8 report the same cloudflare url for this malware site (104.26.9.237). I dunno if a cloudflare bug or a hostile takeover of doi.org

Requires molybdenum.

What kind of implications does that have? Is molybdenum very expensive to use in batteries?

It's quite a bit less common on earth than either Cobalt or Lithium, and currently pretty much all of it is used for metallurgy or lubrication. Roughly an order of magnitude less common than either Cobalt or Lithium (~20ppm vs. 1.5ppm).

EDIT: Also, per wiki, we produce almost 2x the amount per annum of Moly than we do of Cobalt, so presumably we're a lot closer to hitting a ceiling than we are with Cobalt/Lithium.

Can someone explain the science behind why a lithium carbon dioxide battery can at least potentially store seven times as much energy as a lithium-ion one?

Miracle battery breakthrough du jour.

I've been watching this soap opera for years. These announcements keep coming, but nothing I can pop down to Fry's and pick some up.

Let me know when they're on the shelf at Fry's or Best Buy, or I can order them from Amazon.

Well, anything that does suddenly appear in stores or whatever, if you google it, you generally find that it's been in the process of development for 20 or 30 years.

So any given story about an innovation could be perfectly real, just not ready for prime time for a few decades.
