A new kind of battery could revolutionize the world's power usage, allowing a huge range of activities to go electric and making net-zero emissions far more feasible. Lithium-sulfur batteries could solve the problems of lithium-ion batteries used in phones and electric vehicles, now that scientists at Drexel discovered a chemical phase of sulfur that stops battery degradation. These batteries will be lighter and longer-lived than lithium-ion batteries, making long-range EVs commercially viable. Short-haul flights, cargo vessels, and passenger ferries can now all go fully electric. The Drexel team is already looking into making sodium-sulfur batteries which, by removing the need for lithium, will make batteries even more eco-friendly and ensure EV adoption can continue at speed.
