TWICE AS MUCH COMPARED TO WHAT????

TWICE AS MUCH COMPARED TO WHAT????

Compared to a non-hydrous sodium vanadium oxide system.
Yep, I'm just annoyed by lazy headlines.
Every week with the "miracle battery!" headlines. This has been going on for ages and I'm sick of it.
Sodium-ion batteries are not hype though, they are in production use in multiple industries already. They are generally superior to Lithium based batteries in all regards, with the exception of having a bit lower energy density. An equivalent LiFePO4 battery might be 70-80% of the size for the same storage. It's not a big deal for large applications like cars and solar storage.
Charged with fusion power! From space! Made from privately mined asteroids!
And it's got electrolytes!

You can throw any battery in the ocean. The better question is should you?
We are close to finding out why some liquids are blue.


Doesnt matter if the capacity is even less than sodium batteries.
We'll see.
Sodium Ion already does 5000+ cycles. Adding Vanadium is not a scalable material. It is very expensive. 400 cycles steady is not useful information because it needs to do much more. They didn't state a wh/kg density. This is probably not a viable research vector, but "big Vanadium" has proposed a rental model to make Vanadium more scarce for other applications. Flow batteries (a fuel cell with tanks of electrolytes) provides an ultra easy way of recycling/selling the vanadium for traditional uses. Battery rental that forces returning it could be viable.
What is the catch?
Low capacity is my guess.
Dunno if the article is the same I have read a few days ago but the, mentioned "everything" except the comparable capacity to sodium or lithium batteries.
And I can't imagine that the capacity for salty water with tofu remnants is much higher than a sodium battery which is atm serialized for mass production runs (isnt it even available in some capacity as a commercial product?)
What do they do with the Chlorine though?
Clean chickens.
This is a most excellent place for technology news and articles.
