RMIT engineers say they’ve tripled the energy density of cheap, rechargeable, recyclable proton flow batteries, which can now challenge commercially available lithium-ion batteries for capacity with a specific energy density of 245 Wh/kg.
“you don’t need lithium or any other exotic metals”
This is really good news.
Lithium isn’t exactly exotic, it’s the third most common element in the universe.
25th most common on Earth and most of it is in the ocean, which we don’t have a good extraction method for yet.
Edit: how did you come up with Lithium being the 3rd most common in the universe? Oxygen is 3rd and Lithium is 44th most abundant universally.
Sadmy, this is going to disappear… Its always the same with good things
I’m going to let you in on a little secret.
They don’t disappear because of some conspiracy.
They disappear because they don’t do what they claim to. Or they only perform that way in a small scale on a lab bench. Or they are too expensive. Or vastly many other reasons.
I think this xkcd statement is equivalent enough: when someone says that they cured cancer in a petri dish, keep in mind that so does a hand gun.
