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

Green Car Congress

The team’s battery chemistry with the solid electrolyte can potentially boost the energy density by as much as four times above lithium-ion batteries, which translates into longer driving range. The four-electron reaction is enabled by a mixed ion–electron-conducting discharge product and its interface with air.
