Summary: This study aims to prepare and characterize a novel polymer-free gel electrolyte (PFGE) based on fumed silica, and apply it to TiO2 electrochromic devices (ECD). A series of liquid electrolytes with different molar ratios of lithium chloride (LiCl) and ethylene glycol (EG) were prepared, and their ionic conductivities were measured to determine the highest ionic conductivity composition. The optimized composition was used to prepare PFGE by adding fumed silica as the polymer-free gelling agent. ECDs were then prepared by sandwiching PFGE between TiO2 electrochromic electrode and fluorine-doped tin oxide (FTO) counter-electrode, and notable electrochromic properties were observed.

Summary: Solid polymer electrolytes (SPEs) are a promising avenue for flexible lithium-ion batteries. However, the low ionic conductivity of polymers remains a challenge. In this study, SPE/FGO electrolytes were prepared using PEO, polyvinyl alcohol, LiClO4, and graphene functionalized with polyethylene glycol. The presence of functionalized graphene effectively reduced crystallinity, and the samples exhibited adequate ionic conductivity at room temperature.

Summary: The applicability of nanofillers in gel polymer electrolyte (GPE)-based devices has significantly increased in the past decade. However, the development of their applicability in GPE-based electrochromic devices (ECDs) has been limited due to challenges such as optical inhomogeneity, transmittance drop, and poor electrolyte fabrication methodologies. In this study, a reinforced polymer electrolyte tailored through PVDF-HFP, BMIMBF4, and various types of mesoporous SiO2 nanofillers was demonstrated to address these issues.
