A method of fabricating an electrode, the method including the steps of: (i) providing an electrode substrate and an active material; wherein the electrode substrate is a current collector substrate selected from the group consisting of aluminium, copper, silver and gold; and the active material is a first and/or second active material, wherein the first and second active material is independently selected from the group consisting of: metals, metal oxides, ceramics, intermetallic compounds, metalloids, carbon, silicon, including its oxides, alloys, and composites, and mixed metal oxides; (ii) contacting one or both of the current collector substrate and the active material with a metal-coordination complex; wherein the metal ion of the metal-coordination complex is selected from the group consisting of chromium, ruthenium, iron, cobalt, aluminium, zirconium, and rhodium ions; and (iii) coating the current collector substrate with the active material, to thereby form the electrode; wherein the metal-coordination complex is in contact, through dative bonds, with the active material and the current collector substrate; wherein the active material further comprises a binder and wherein, when the active material additionally comprises both silicon nanopowder and a conductive carbon black and the current collector substrate is a copper foil, then the binder is not Poly(acrylic acid) (PAA).
