Sol-gel derived lithium salt (LiClO4) doped organic-inorganic hybrid electrolytes have been obtained from the tetraethyl orthosilicate (TEOS) and poly(ethylene oxide) (PEO), propylene oxide (PO), ethyl acetoacetate (EAA), propylene carbonate (PC), polyvinyl alcohol (PVA) precursors and have been investigated for morphology and structural properties by SEM/EDS and FTIR spectroscopy. The hybrid materials obtained were amorphous, with structural properties influenced by organic ingredients which had been used, and with the ionic conductivities of 10-4-10-3 Scm-1. When used as electrolytes in the WO3-based thin-film electrochromic coatings, they have proved to be suitable for low-temperature electrochemical applications.
