Abstract : Thin solid films of mixtures of PEGDME and PEO containing various ratios of ZnBr2 and LiBr have been prepared Equal parts of PEGDME and PEO were used, and the ether oxygen to total metal ratio was kept constant at 16. TG data have shown that the thermal stability of the polymer electrolytes is affected more so by the zinc salt than the lithium salt DSC data show that these electrolytes are inhomogeneous mixtures of amorphous regions and crystalline PEO and PEO/salt complexes. Conductivity data did not show a mixed-cation effect.
