Abstract
A solid electrolyte for a negative electrode of a secondary battery includes a first porous solid electrolyte having a first surface; a first coating on the first surface of the first porous solid electrolyte; an adhesive electrolyte layer on the first porous solid electrolyte; and a second porous solid electrolyte on the adhesive electrolyte layer, the second porous solid electrolyte having a second surface; wherein the first porous solid electrolyte and the second porous solid electrolyte each have an ionic conductivity effective for a deposition metal; and wherein a surface of the first coating is less favorable for deposition of the deposition metal than the second surface of the second solid electrolyte. An electrode assembly and an electrochemical cell including the solid electrolyte and method for the manufacture thereof are also described.
