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.

MIT team synthesizes all carbon nanofiber electrodes for high-energy rechargeable Li-air batteries

Green Car Congress

The carbon nanofiber electrodes are substantially more porous than other carbon electrodes, and can therefore more efficiently store the solid oxidized lithium (Li 2 O 2 ) that fills the pores as the battery discharges. In that work, the carbon structures were more complex but only had about 70% void space.
