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.

Abstract: An electrode is provided having a front region adjacent to a separator and a back region adjacent to a current collector. The electrode includes an anion-absorbing material and a cation-absorbing material. The electrode exhibits a compositional profile such that the anion-absorbing material is present at a higher volume percent at the back region than at the front region. Also provided are electrochemical cells that employ such an electrode as a positive electrode. Optionally, the cells include an electrolyte comprised of a solution of a solvent and a salt dissolved therein at a concentration of at least about 2M when the cell is in a fully discharged state.

Abstract: A solid electrolyte for a negative electrode of a secondary battery includes a first solid electrolyte having a first surface and a second solid electrolyte on the first solid electrolyte and having a second surface. The first solid electrolyte and the second solid electrolyte each have an ionic conductivity effective for a deposition metal, and the first surface and the second surface are different in composition, structure, or both. An electrode assembly and an electrochemical cell including the solid electrolyte and method for the manufacture thereof are also described.
