Did I miss that or are you saying it rhetorically? I didn’t pull the actual scientific article but this one mentioned decent performance over 800 cycles and 100 mAh/g. I’m not really up on this kind of tech but that seems pretty nifty for a new chemistry .
If you were just being rhetorical I get the frustration. There’s always gremlins hiding somewhere.
Still, I take stuff like this as indicitive that were absolutely not going to be stuck with Li ion forever.
Yeah I suppose thats true, I mean without a power curve the OCV isn’t all that interesting to me (and that power curve is going to be influenced by manufacturing which is probably not optimized and may or not be compatible etc etc). So like I said, neat bit of chemistry, but I do get why people get burned out on these articles.
Salt batteries are really bad, but, you know, at least they’re salt. I don’t know much about salt batteries at the expert level, but I also work on an e-chem system that is low current low density. There’s definitely applications, especially because materials and tanks are cheap, but it turns out power is stupid cheap as well.
I don’t think anyone can really predict a new “winner” right now, but it’s the biggest reason why I’m a proponent of electronification in general; we absolutely won’t be tied to Lithium forever.
This sounds like it’s worth the hype to me. It has about the same energy density as lithium-ion, and it uses non-toxic and abundantly available materials (unlike lithium-ion).
The cycle count is a little poor but it’s in the ballpark of lithium-ion, is likely to get better, and is much less of an issue if the batteries are non-toxic.
Also… the fact it’s non toxic could effectively reduce the weight especially for small batteries (where they’re still not safe enough despite heavy enclosures - kids literally die after swallowing coin cell lithium batteries).
I’d say worth discussing but none of these articles are ever “hype” worthy. Its really cool to know about, and should point to a brighter future, but there are always gremlins in this kind of thing. Even fuel cells, which have a deserved reputation on WAY over hyping early, helped lay the groundwork for a lot of manufacturing infrastructure and technical know how that laid the work for a lot of the battery boom we saw and continue to see.

The mAh/g might be comparable, but it’s only 1V per cell. Lithium cells are 3.3V per cell, so the overall Wh/kg is worse than three times lower.
Since it’s made of cheap and abundant materials, it could still be useful for grid storage, or for a cheap commuter EV.

I’m like, how bad are salt water batteries that this is an “achievement”?

Sorry, I was definitely being rhetorical. I’m happy to see research continue, I just tire of the hype…
