Abstract
A method of manufacturing a thin film is provided. The method includes providing a plurality of crystalline cathodic electrochromic particles comprising an alkali metal oxide material, size-reducing the crystalline cathodic electrochromic particles by grinding to produce crystalline cathodic electrochromic nanostructures, providing a substrate, and coating the crystalline cathodic electrochromic nanostructures onto the substrate to produce a thin film, wherein the thin film is an electrochromic thin film.
