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.

St. Andrews team elucidates behavior of carbon cathodes in Li-air batteries; the importance of the synergy between electrode and electrolyte

Green Car Congress

Carbon is seen as an attractive potential cathode material for aprotic (non-aqueous) Lithium-air batteries, which are themselves of great interest for applications such as in electric vehicles because of the cells’ high theoretical specific energy. Given the role of carbon as a possible porous positive electrode for nonaqueous Li?
