X‐Ray Absorption Studies of Mixed Salt Polymer Electrolytes: , , and Complexes

Abstract
X‐ray absorption (XAS) studies of complexes, at the Zn K edge, at temperatures between 25 and 120°C, indicate that additions of bromide salts of Li, Rb, or Ca result in the formation of complexes with a Zn‐Br bond length of 2.42 Aå. XAS, at the Rb K edge, in mixed complexes with an excess of , shows that the causes the to dissolve in the polymer. The Rb+ ions are weakly complexed with the PEO with an Rb‐O bond distance of 2.93 Aå.
