Composite Polymer electrolytes (CPEs) have served as the focus of intensive research for the next-generation energy storage devices, as they have the advantage of preventing the Li dendrite formation compared with conventional liquid electrolytes. However, inorganic ceramic component generally made CPEs have low ionic conductivity and the high brittleness. Here, a commercially available epoxy is combined with a mixture of Li salt (LiTFSI) with glyme (G4) and silica mesoporous particles (SMP), using the ring-opening polymerization. The SMP as a filler can provide further high mechanical property without significant decrease of ionic conductivity by incorporated into the epoxy-based CPEs. We systematically investigated the effect of SMP content on the ion conduction, dielectric respons, and thermal property using electrochemical impedance spectroscopy, dielectric spectroscopy, and differential scanning calorimetry, respectively. |
