edit I am an idiot, who uploaded the image link as the URL. The original source should now be accessible

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.

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.

Huh, I guess I was wrong. Lithium was one of the first elements created in the universe, and it turns out it's lack of abundance in the current universe is a problem.
