Single-crystal orientation lithium for ultra-stable all-solid-state batteries.

ABSTRACT: All-solid-state lithium (Li) metal batteries (ASLMBs), particularly with inorganic solid electrolytes, possess both high energy density and high safety. However, their practical application is still being severely impeded by Li dendrite formation as a fundamental but unclear issue. Here, we reveal that the anisotropic exfoliation of polycrystal Li metal due to different energies required for Li atom stripping from various Li crystal planes leads to the formation of voids upon cycling, which is the intrinsic cause for the formation of Li dendrites and interfacial cracks. We thereafter precisely tune the polycrystal Li metal to <110>-oriented single-crystal Li metal using a lattice-matching template of Li₂Ga (131) interface. During the stripping process of <110>-oriented single-cr
