Lithium-metal solid-state batteries offer advantages of high energy density and improved safety compared with lithium-ion batteries,. However, solid-state batteries fail through short-circuiting even at low charging rates (less than 1 mA cm− 2) due to lithium dendrite initiation and propagation,–. The location of dendrite initiation is under debate, particularly regarding whether initiation occurs within the interior of the solid electrolyte,,–or at the surface,,,–. Here we develop an in-plane biaxial compression method that provides direct evidence that …
