New nickel oxide thin films with a micro-scale thickness and porous structure were fabricated using a sol–gel method in a mixed solvent containing N,N-dimethylaminoethanol (dmaeH) and distilled water at a 1:1 ratio. After annealing, the deposited film transformed to a well oriented, porous nickel oxide thin film. This nickel oxide thin film showed enhanced charge capacity and greater optical transmittance changes in a lithium-based electrolyte, and may be applied to WO3/Li+-based electrolyte/NiO electrochromic devices requiring long cycles.
Graphical abstractThe nickel oxide thin films with a micro-scale thickness and porous structure were fabricated using a sol–gel method in a mixed solvent containing N,N-dimethylaminoethanol (dmaeH) and distilled water at a 1:1 ratio. This nickel oxide film showed enhanced electrochromic properties in a Li+-based electrolyte, and it also presented excellent performance in WO3/Li+-based electrolyte/NiO electrochromic devices .Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Porous thick nickel oxide thin films were prepared by a sol–gel method using an aqueous solution. ► This nickel oxide film showed good optical transmittance change and coloration efficiency. ► The electrochromic device showed good performance and durability with a Li-based electrolyte.
