Using mathematical modeling, an international team of researchers (China, USA – University of Delaware, Boston University, Utah State University) fabricated a membrane made of tiny wires of porous silicon nitride that measured less than one millionth of a meter each, to suppress the initiation and growth of dendrites. They integrated this membrane into lithium metal cells in a battery and ran it for 3,000 hours without growing dendrites. The principle may also extend to other battery systems, such as zinc or potassium-based batteries… read more. TECHNICAL ARTICLE
Through simulations and experiments, the research team showed that a porous membrane stifled the formation of dendrites in lithium metal batteries. Credit: University of Delaware/ Illustration by Joy Smoker
