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.

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.

    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.
