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.

This translates to an energy enhancement ~4 times greater than the state-of-the-art lithium intercalation compounds such as LiCoO 2 (~600 W h kg electrode -1 , the researchers said. In that work, the carbon structures were more complex but only had about 70% void space. ” Resources. ” Resources. Mitchell, Betar M.

Recently, researchers have also found out the instability of electrolyte and carbon electrode under the high charging potential (>3.5 V), which contributes to the low rechargeability. But the necessity of catalysts has been argued, because the catalyst on carbon may not be able to work once its surface is blocked.

MIT Researchers Report Progress on Catalyst Development for Lithium-Air Batteries

Green Car Congress

A team of researchers at MIT led by Professor Yang Shao-Horn have found that gold-carbon (Au/C) and platinum-carbon (Pt/C) catalysts have a strong influence on the charge and discharge voltages of rechargeable lithium-air (Li-O 2 ) batteries, and thus enable a higher efficiency than simple carbon electrodes in these batteries.
