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.

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. This remains a core challenge that needs to be overcome for the viable commercialization of Li-air technology.

Researchers directly visualize formation and disappearance of Li-O2 reaction products; insights to support development of rechargeable lithium-air batteries

Green Car Congress

During discharge and charge in UHV, Li ions reversibly intercalate/de-intercalate into/from the Li x V 2 O 5 electrode. During discharge, Li ions meet with reduced oxygen on the surface of the Li x V 2 O 5 electrode forming Li 2 O 2 , which is decomposed upon recharge. The rechargeable Li?air
