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

Green Car Congress

The battery is rechargeable for 1000 cycles with a low polarization gap and can operate at high rates. 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.

3D self-assembling nanostructure for cathodes enables very rapid charge and discharge without sacrificing capacity; potential for EVs

Green Car Congress

Researchers at the University of Illinois at Urbana-Champaign have developed a self-assembling three-dimensional nanostructure for battery cathodes (Li-ion and NiMH) that allows for faster charging and discharging without sacrificing energy storage capacity. Most capacitors store very little energy. This does both.

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

Researchers at The Ohio State University have developed a novel strategy to improve the efficiency and performance of non-aqueous lithium-oxygen (Li-air) batteries. O 2 systems require an open system to obtain oxygen from the air; Li metal must also be used as the metal electrode to provide the lithium source. Earlier post.).
