Researchers directly visualize formation and disappearance of Li-O2 reaction products; insights to support development of rechargeable lithium-air batteries

Green Car Congress

During discharge, Li ions meet with reduced oxygen on the surface of the Li x V 2 O 5 electrode forming Li 2 O 2 , which is decomposed upon recharge. The rechargeable Li?air The observational method this team developed could have implications for studying reactions far beyond lithium-air batteries, Yang Shao-Horn, the Gail E.

Univ. of St. Andrews researchers show reversible, higher-rate non-aqueous Li-air battery using gold cathode and DMSO electrolyte

Green Car Congress

Very high energy density rechargeable lithium air (or Li-O 2 ) batteries are of great interest for future electrified transportation because at best their practical energy density could approach that of current gasoline engined vehicles (after factoring in tank-to-wheel efficiencies). Earlier post.). Earlier post.).
