| Electrochromic windows and solid state microbatteries are based on intercalation and ion conducting thin films. Their development is nowadays mainly limited to research environments due to inadequate performance of these components. Intercalation materials with better reversibility and ion conductors with higher ionic conductivity are required for further development.;This work proposed new thin film materials for applications in solid state microbatteries and electrochromic windows: titanium oxysulfide as intercalation layer, and lithium niobiom oxynitride as ionic conductor. Film properties and structure were studied by x-ray diffraction, electrochemical potential spectroscopy, complex impedance analysis, spectroscopic photometry, and ellipsometry.;Studies showed that titanium oxysulfide films are amorphous, transparent, and remarkably reversible intercalation electrodes. Films of thickness about 150 nm can store up to 200 ;Lithium niobium oxynitride films, having room temperature ionic conductivity as high as ;The obtained results show that the proposed materials are promising candidates for intercalation cathode and ion conductor in both electrochromic windows and microbatteries. However, further works are required to investigate their behavior when they are incorporated into complete devices. More elaborate structural and compositional studies will also provide valuable information for their applications. |
