AIST Developing New Lithium-Air Battery; Lithium Fuel Cell

Green Car Congress

Long-term discharge curve of the newly developed lithium-air cell. Researchers at Japan’s AIST (National Institute of Advanced Industrial Science and Technology) are developing a lithium-air cell with a new structure (a set of three different electrolytes) to avoid degradation and performance problems of conventional lithium-air cells.

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

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.

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

Green Car Congress

The surfaces of Li 2 O 2 are free of carbonate species formed on the surface of the LLTO/LiPON/Li x V 2 O 5 cell, which is in contrast to the coverage of Li 2 CO 3 -like species on Li 2 O 2 particles even with ether-based electrolytes.

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. Mitchell, Betar M. Gallant, Carl V.
