AB  - In this paper, solution casting method is used to prepare the PP (polypropylene) 
      non-woven fabric based composite film filled with silicon dioxide/polyvinylidene 
      fluoride (SiO(2)/PVDF). The mechanical and thermodynamic properties of 
      PP/SiO(2)/PVDF composites were studied by a uniaxial tensile test under different 
      temperature and combustion experiment. It is found that the stress of 
      PP/SiO(2)/PVDF composite film with 4 wt % SiO(2) is the maximum value, reaching 
      18.314 MPa, 244.42% higher than that of pure PP non-woven. Meanwhile, the 
      thermal-mechanical coupling tests indicate that with the increase of temperature, 
      the ultimate stress and strain of the composite decrease. At the same time, the 
      thermal shrinkage property of the composite during the heating process is 
      studied. The modified composite has good thermal stability under 180  degrees C. Scanning 
      electron microscope (SEM), X-ray diffraction (XRD) and thermogravimetric (TG) 
      were used to characterize the pore shape, distribution and crystal phase change 
      of the composite. The modified PP/SiO(2)/PVDF composite film structure shows high 
      strength and good thermal stability, and can better meet the requirements of 
      strength and thermal performance of lithium-ion battery during the charging and 
      discharging process.
