Impact of the NaClO 4 /NaPF 6 salt ratio on the structure, mechanical and conductive properties of the PEO:(NaClO 4 ) 1− x (NaPF 6 ) x solid polymer electrolyte

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.
