With real uncertainty clouding the world's supply of lithium, alternative battery chemistries will be crucial as we continue our uptake of electric vehicles and mobile devices. One exciting candidate ...

Fuel cells powered with the metal could provide a new source of electric power that's far more energy-dense than lithium-ion batteries. A new type of fuel cell that runs on sodium metal could one day ...

What if the future of aviation didn’t rely on heavy lithium-ion batteries or complex hydrogen systems, but instead on a fuel as simple and abundant as sodium? At MIT, researchers are turning this bold ...

Electric vehicles are colliding with a hard reality: lithium is expensive, supply chains are fragile, and safety concerns still unsettle buyers. A new generation of solid-state sodium-ion batteries ...
