IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

Researchers at the Illinois Institute of Technology (IIT) and US Department of Energy’s (DOE) Argonne National Laboratory have developed a lithium-air battery with a solid electrolyte. A lithium-air battery based on lithium oxide (Li 2 O) formation can theoretically deliver an energy density that is comparable to that of gasoline.

PNNL team uncovers reaction mechanisms of Li-air batteries; how batteries blow bubbles

Green Car Congress

Lithium-air batteries are looked to by many as a very high-energy density next-generation energy storage solution for electric vehicles. One reaction that hasn’t been fully explained is how oxygen blows bubbles inside a lithium-air battery when it discharges. The paper is published in the journal Nature Nanotechnology.

Argonne-led team demonstrates Li-air battery based on lithium superoxide; up to 5x Li-ion energy density

Green Car Congress

Lithium-air batteries form lithium peroxide (Li 2 O 2 )—a solid precipitate that clogs the pores of the electrode and degrades cell performance—as part of the charge−discharge reaction process. We have to learn how to design catalysts to understand exactly what’s involved in lithium-air batteries.
