High-conductivity Hydrophobic Fumed-SiO2 Composite Gel Electrolyte for High Performance Electrochromic Devices
Source abstract
Abstract
Gel electrolytes are chemically stable, nonflammable and easy to encapsulate, however, their moderate ionic conductivity (10 -4 -10 -5 Scm -1 ) hinders their further development for the usage in electrochromic devices (ECDs). Here, we developed a highly conductive hydrophobic SiO 2 /PMMA/PC/LiClO 4 gel polymer electrolyte (H-SiO 2 GPE). Electrochemical behaviors of ECDs were characterized by electrochemical impedance spectroscope (EIS), cyclic voltammetry (CV) and chronoamperometry (CA). Systematic analyses show that the ionic conductivity of the H-SiO 2 GPE can reach 5.14 mScm -1 (at 25 ) by introducing only 0.5wt% hydrophobic fumed SiO 2 . This increase is due to the good compatibility and hydrophobic-hydrophobic attractions between SiO 2 additive and organic electrolyte, which promotes the dissociation of lithium perchlorate. Additionally, the viscosity as a function
