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

Green Car Congress

In past lithium-air designs, the lithium in a lithium metal anode moves through a liquid electrolyte to combine with oxygen during the discharge, yielding lithium peroxide (Li 2 O 2 ) or superoxide (LiO 2 ) at the cathode. —co-author Rachid Amine More electrons stored means higher energy density. —Kondori et al.

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

Stanford / SLAC’s new lithium-polysulfide flow battery design compared to conventional “redox” flow batteries. Unlike previous work on Li/S batteries with discharge products such as solid state Li 2 S 2 and Li 2 S, the catholyte is designed to cycle only in the range between sulfur and Li 2 S 4.
