a Scenarios of dendrite loading and Mode I loading. b Normal stress distribution in the LLZO under dendrite loading (t = 0.6 ns) and Mode I loading. c Calculated critical stresses under dendrite loading (t = 0.6–0.75 ns) and Mode I loading. d Atomic structure of lithium metal inside the dendrite during deposition. e Fraction curves of different crystalline types inside the dendrite. f Schematic representation of the transition process of lithium metal atomic stacking structures, starting from the BCC (left) configuration, moving to the disordered configuration (center), and finally transitioning to the HCP and FCC configurations (right). g Stress distribution inside the dendrite.
