abstract = " The NaClO 4 /NaPF 6 combination improves the mechanical properties of SPE films without loss of conductivity. The composition PEO 12.5 :(NaClO 4 ) 0.5 (NaPF 6 ) 0.5 has conductivity similar to that of PEO 12.5 :NaClO 4 , but the E value is 10 times higher. In this work, a comparative study of the solid polymer electrolytes (SPEs) PEO:(NaClO 4 ) 1− x (NaPF 6 ) x was carried out. It was shown that the NaClO 4 /NaPF 6 salt ratio can modify the phase composition, thermal behaviour, local structure, and mechanical and conductive properties of the SPEs. Increasing the NaPF 6 content leads to the formation of an additional crystalline phase, PEO–NaPF 6 , which affects the number of free charge carriers according to the FTIR data. A non-linear change in the conductivity of the solid polymer electrolyte PEO 12.5 :(NaClO 4 ) 1− x (NaPF 6 ) x was observed. For the compositions with x < 0.5, the change in conductivity was insignificant. When x > 0.5, a gradual decrease in conductivity was observed. It was shown that increasing the crystalline part of the SPE results in a significant improvement in the mechanical properties of the SPE. The study of the SPEs with different salt ratios allowed us to determine the range in which there is a significant increase in the mechanical strength of the SPE without loss of conductivity. ",
