A nanostructured lithium‐metal anode employing an unstacked graphene “drum” and dual‐salt electrolyte brings about a dendrite‐free lithium depositing morphology. On the one hand, the unstacked graphene framework with ultrahigh specific surface area guarantees an ultralow local current density that p...
