1. A substrate comprising a nanostructured coating layer, prepared by a method comprising:
(a) immersing the substrate in an aqueous solution that comprises one or more dissolved metal salt(s) at a temperature from about 50° C. to about 90° C., under conditions such that a nanostructured layer is deposited on the substrate, thereby producing a coated substrate,
wherein the aqueous solution comprises 2+ and/or 3+ ion(s) of one or more first metal(s), wherein the 2+ and/or 3+ first metal ion(s) are derived from the one or more dissolved metal salt(s), and wherein the nanostructured layer comprises one or more of the 2+ and/or 3+ first metal ion(s) from the aqueous solution, and
wherein the substrate comprises one or more second metal(s) with 2+ and/or 3+ primary oxidation state, wherein the first metal(s) and the second metal(s) are different, and wherein the nanostructured layer comprises one or more 2+ and/or 3+ ion(s) of the second metal(s) from the substrate;
(b) separating the coated substrate comprising the nanostructured layer from the solution; and
(c) treating the coated substrate to stabilize the nanostructured layer and/or to prepare the nanostructured layer for subsequent processing,
wherein step (c) comprises one or more processing steps to replace anionic and/or cationic components of the coated substrate, or comprises thermal processing, oxidation, or reduction of the coated substrate; and
(d) depositing one or more additional material(s) onto the nanostructured layer, wherein the nanostructured layer enhances the performance of an electrochemical cell, in comparison to an identical electrochemical cell that does not comprise the nanostructured layer,
wherein the one or more additional material(s) comprises copper, cobalt, nickel, manganese, and/or alloys thereof.
