Abstract
Provided is a solid electrolyte membrane for a solid-state battery, including at least two solid electrolyte layers and at least one volume-swelling layer, wherein the volume-swelling layer is disposed between the solid electrolyte layers. The solid electrolyte membrane includes (a) an ion conductive solid electrolyte material, and the volume-swelling layer includes (b) inorganic particles, wherein the inorganic particles form an alloy with lithium and include a metal, metal oxide or both. Thus, it is possible to provide a solid electrolyte membrane for a solid-state battery fundamentally prevented from a short-circuit by inhibiting growth of lithium dendrite.
