ELECTROLYTE MEMBRANE FOR ALL-SOLID-STATE BATTERY, AND ALL-SOLID-STATE BATTERY INCLUDING SAME

The present disclosure relates to a solid electrolyte membrane for an all-solid-state battery and a battery comprising the same. In the present disclosure, the battery may comprise lithium metal as a negative electrode active material. The solid electrolyte membrane for an all-solid-state battery according to the present disclosure comprises a guide layer comprising metal particles to guide the horizontal growth of lithium dendrites, thereby delaying an electrical short caused by dendrite growth. Additionally, the guide layer is formed by polymer self-assembly, and thus the metal particles may be uniformly distributed in a very regular pattern within the guide layer.
