From: Direct observation of lithium metal dendrites with ceramic solid electrolyte

(a) Cross-section mapping of LLZO under the Li electrode after cycling, showing inhomogeneous distribution of Zr, La, and C, (b) Schematic of a cross-section of the top Li and LLZO before and after cycling. After cycling an inhomogeneous distribution of Zr, La, and C was observed, indicating La2Zr2O7 segregation. Close-up schematic shows one region containing bump and needle dendrite morphologies that appear close to electrode areas where Li thinning occurs.
