Catalyst development for lithium-air batteries

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-O2) batteries, and thus enable a higher efficiency than simple carbon electrodes in these batteries.

In a paper published 1 April in the journal Electrochemical and Solid-State Letters, the team reports that Li–O2 single-cell measurements showed that Au/C had the highest discharge activity, while Pt/C exhibited extraordinarily high charging activity.
