ALS Technique Gives Novel View of Lithium Battery Dendrite Growth
Lithium-ion batteries, popular in today’s electronic devices, could gain significant energy density if their graphite anodes were replaced with lithium metal anodes. But there’s a major concern with substituting lithium—when the battery cycles, microscopic fibers of the lithium anodes (“dendrites”) form on the surface of the lithium electrode and spread across the electrolyte until they reach the other electrode, possibly leading to short circuiting. Researchers have recently discovered that the x-ray microtomography capabilities at ALS Beamline 8.3.2 can give them a novel view of dendrite growth that’s likely to provide the insight needed to stop it.
