Better red than dread: Barrier keeps batteries safe

A layer of red phosphorus in rechargeable lithium metal batteries can signal when damaging dendrites threaten to create a short circuit. The technique developed at Rice University could lead to more powerful lithium metal batteries. Image: Tour Group/Rice University

Half-cell lithium metal battery show dendrites approaching a red phosphorus separator. The separator delivers a signal to the battery's electronics to shut down when dendrites threaten to create a short circuit. The discovery could help make lithium batteries safer. (Tour Group/Rice University)
