Abstract The polyacrylonitrile based gel polymer electrolyte (PAN-EGDMA-GPE) cross-linked by ethylene glycol dimethacrylate (EGDMA), and the PAN-EGDMA-GPE composited with the non-woven fabrics (NWF-PAN-EGDMA-GPE) were successfully prepared by in-situ polymerization. The molecular structure, thermal properties, tensile strength and ionic conductivity of GPE films were detected with the infrared spectrometer, integrated thermal analyzer, universal testing machine and electrochemical workstation. The results showed that the tensile strength of GPE films were significantly improved by EGDMA cross-linker and PP non-woven fabrics. When the amount of EGDMA used was 2.5%( weight) of the monomer, the concentration of LiClO₄ was 1 mol/L, and the electrolyte mass content was 87.5% of PAN-EGDMA-GPE, the NWF-PAN-EGDMA-GPE film had the comprehensive performance, the tensile strength of that was 8.47 MPa, which was increased by 31.6 times, comparing to the 0.26 MPa of the unreinforced polyacrylonitrile GPE, the ionic conductivity of that was 1.24×10^-3 S/cm.
