Energetics Dictates Deposition At Metal/Solid Electrolyte Interfaces
JOURNAL OF PHYSICAL CHEMISTRY C(2021)
摘要
Solid electrolytes are promising toward utilizing lithium metal anodes with high specific capacity and low redox potential. The solid electrolytes are expected to provide a mechanical barrier, thereby dwarfing lithium metal dendrite growth. However, dendrite penetration through solid electrolytes has been reported. In this work, we present a comprehensive description of the role of interface energetics in determining the deposition morphology at the metal/solid electrolyte buried interfaces. If the interaction between the solid electrolyte and metal surfaces at the interface is weak, then the morphology of the metal surface is rough after deposition. Conversely, for a strongly interacting interface, a flat interface is obtained. The energy of the total system is limited to a small region near the interface, and the bulk of the metal away from the interface is free of distortion and has negligible energy. The strength of the energetic interaction at the metal and solid electrolyte interface primarily determines the deposition morphology.
