For next-generation energy storage devices, mechanical robust solid polymer electrolytes (SPEs) have attracted widespread attention due to their good processability, low cost, and dimensional stability. However, they are generally appeared a trade-off characteristic between mechanical property and ionic conductivity. Herein, the cross-linked epoxy-based SPEs containing Li salt (LiTFSI) with glymes (G3 or G4) and Ionic liquid (IL), using the ring-opening polymerization. The glymes are chosen to dissociate the Li ion from LiTFSI salt, and the IL is selected to enhance ionic conductivity. Furthermore, the epoxy resin can provide high mechanical and thermal properties. The effect of ionic liquid types on mechanical and thermal properties, ionic conductivity, and morphology characterized by using DMA, DSC, TGA, dielectric spectroscopy, and Fe-SEM, respectively. |
