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

Green Car Congress

This study showed that using metal oxides as the oxygen electrode could potentially enable a lithium-air battery to maintain its performance over many cycles of operation. The observational method this team developed could have implications for studying reactions far beyond lithium-air batteries, Yang Shao-Horn, the Gail E.

UK report sees step-change improvements in performance of EV batteries as “highly unlikely” through 2020

Green Car Congress

The report— Cost and performance of EV batteries —describes the current state of development and cost of batteries, before mapping the future cost and performance of lithium-ion batteries out to 2030. In 2030, under a baseline scenario, this is predicted to drop to $6,400 for a BEV with a range of 250 km (155 miles).
