Dw. Pollock et al., ION-PAIRING AND IONIC-CONDUCTIVITY IN AMORPHOUS POLYMER ELECTROLYTES - A STRUCTURAL INVESTIGATION EMPLOYING EXAFS, Chemistry of materials, 6(11), 1994, pp. 1912-1914
A strong inverse correlation between ion pairing, determined by EXAFS,
and the bulk ionic conductivity of amorphous poly(ethylene oxide)-CuC
l2 polymer electrolytes, aPEO:CuCl2, is reported. The conductivity of
the polymer electrolytes and the degree of ion pairing has been observ
ed as a function of salt concentration. Cu2+-Cl- ion pairs were observ
ed even in the most dilute polymer electrolyte (44 O:1 Cu2+).
