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

Document Type and Number:

WIPO Patent Application WO/2020/214016

Kind Code:

A1

Abstract:

The present invention pertains to: a solid electrolyte membrane for an all-solid-state battery; and a battery including same. In the present invention, the battery may include lithium metal as a negative electrode active material. The solid electrolyte membrane for an all-solid-state battery according to the present invention is provided with a guide layer containing metal particles. Accordingly, lithium dendrites grow in the horizontal direction, and thus there is the effect that electrical shorts caused by dendrite growth are delayed. In addition, since the guide layer is formed through self-assembly of a polymer material, metal particles can be uniformly distributed in a very uniform pattern in the guide layer.
