1. A method for depositing a thin film comprising an artificial solid-electrolyte interphase (SEI) onto a surface of a solid-state electrolyte or a solid-state-electrolyte-electrode composite matrix, the method comprising:
(a) providing the solid-state electrolyte or the solid-state-electrolyte-electrode composite matrix onto a conveyance apparatus;
(b) transferring, by the conveyance apparatus, the solid-state electrolyte or the solid-state-electrolyte-electrode composite matrix to a first reaction chamber containing a first liquid solution comprising at least a first reagent;
(c) exposing, by the conveyance apparatus, the solid-state electrolyte or the solid-state-electrolyte-electrode composite matrix to the first liquid solution in the first reaction chamber to yield a layer partially coated with the at least first reagent chemically bonded onto the surface of the solid-state electrolyte or the solid-state-electrolyte-electrode composite matrix;
(d) rinsing, in the first reaction chamber, the layer with a first rinsing solution comprising a first solvent to remove unreacted first reagent;
(e) transferring, by the conveyance apparatus, the solid-state electrolyte or the solid-state-electrolyte-electrode composite matrix from (d) to a second reaction chamber containing a second liquid solution comprising at least a second reagent;
(f) exposing, by the conveyance apparatus, the solid-state electrolyte or the solid-state-electrolyte-electrode composite matrix to the second liquid solution in the second reaction chamber, wherein the at least second reagent reacts with the at least first reagent chemically bonded onto the surface of the solid-state electrolyte or the solid-state-electrolyte-electrode composite matrix to produce the artificial SEI thin film comprising a monolayer on the surface of the solid-state electrolyte or the solid-state-electrolyte-electrode composite matrix, the monolayer comprising a compound generated from the reaction of the at least first reagent and the at least second reagent; and
(g) rinsing, in the second reaction chamber, the artificial SEI thin film with a second rinsing solution comprising a second solvent to remove unreacted second reagent.
