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. During the charging process, the reduced form of the redox shuttle, M red , is first converted to M ox on the oxygen electrode, which in turn oxidizes the Li 2 O 2.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

Today’s technologies for making biofuels all rely on photosynthesis—either indirectly by converting plants to fuels or directly by harnessing photosynthetic organisms such as algae. This process is less than 1% efficient at converting sunlight to stored chemical energy. Ohio State Univ. Engineering E. coli; Product: Isooctane.
