Cornell study examines trade-off between critical metals requirement and transportation decarbonization

Green Car Congress

A team from Cornell, with a colleague from Paul Scherrer Institute, has analyzed the trade-off between the decarbonization potential of the road transportation sector and its critical metal requirement from the demand-side perspective in 48 major countries committing to decarbonize their road transportation sectors aided by electric vehicles (EVs).

St. Andrews team elucidates behavior of carbon cathodes in Li-air batteries; the importance of the synergy between electrode and electrolyte

Green Car Congress

Carbon is seen as an attractive potential cathode material for aprotic (non-aqueous) Lithium-air batteries, which are themselves of great interest for applications such as in electric vehicles because of the cells’ high theoretical specific energy. For their study, they cycled carbon cathodes in Li?O
