Abstract: A method for forming a solid electrolyte coating on a substrate (1), the method comprising: a. providing a first and a second electrode (3), b. coating a sol-gel precursor solution (4) of the solid electrolyte coating on the substrate (1) and electrically contacting the sol-gel precursor solution (4) with the first and the second electrode, the sol-gel precursor solution (4) being capable of forming a gel in presence of a voltage, and c. generating the voltage across the sol-gel precursor solution (4) via the first and the second electrodes, thereby transforming the sol-gel precursor solution (4) into a gel.

Abstract: A coated three-dimensional electronically conductive network for acting as an electrode in a metal or metal-ion battery is provided, wherein the metal may include one or more of Na, K, Li, Ca, Mg, and Al. The network can be a three-dimensional electronically conductive network that includes a plurality of interconnected electronically conductive wires. Such a network can have a porosity of at least 60% and a volumetric surface area of from 10−3 m2/cm3 to 100 m2/cm3. The network can additionally include an electronically insulating coating that conformally covers all surfaces of the network and that is permeable and/or conductive to ions of the metal at at least one temperature in the range of from −30° C. to 150° C.
