Claim 12:
13. A method of making a solid-state electrolyte for a battery cell, comprising:
a) depositing one of:
i) a solid bulk electrolyte layer comprising carbon-doped LiPON or WO3+x, wherein 0≤x≤1, and
ii) a solid anode interface layer comprising lithium phosphorus oxynitride (LiPON) or a metal oxide that forms a stable complex oxide with lithium oxide and conducts lithium ions when lithiated,
on an active layer of the battery cell; and

b) depositing the other of the solid bulk electrolyte layer and the anode interface layer on the one of the solid bulk electrolyte layer and the anode interface layer,
wherein the anode interface layer has a thickness less than that of the bulk electrolyte layer.
