Following previous work from Cambridge University, the US Department of Energy's Argonne National Laboratories has announced a breakthrough in the development of Lithium-Oxygen battery chemistry.

They have demonstrated the ability to stabilize crystalline lithium-superoxide, while avoiding lithium peroxide, which could usher in an entirely new class of batteries.
"The key advantage of a battery based on superoxide, according to the two researchers, is that it enables what is known as a "closed system," which stands in contrast to open systems that require a constant intake of oxygen from the environment. This makes closed system batteries far safer and more efficient.
"This discovery really opens a pathway for the potential development of a new kind of battery," said Curtiss. "Although a lot more research is needed, the cycle life of the battery is what we were looking for.""
Lithium-Air chemistry has been estimated to potentially contain 5-to-15 times the energy density of Lithium-Ion, partly because Lithium-Air consumes Oxygen from the air.
This "closed system" will not have that advantage, so it's energy density will probably be at the low end of the range.
Five times the capacity of a Lithium-Ion, that really is a breakthrough, approaching half of gasoline's.
