摘要：

Ca(SO3Cl)(2) is synthesised via a new procedure using CaCl2, SOCl2 and chlorosulphuric acid. The synthesised salt is used in preparation of ion conducting electrolyte (PEO)(4)Ca(SO3Cl)(2) film. Ca K-edge EXAFS results show that in the chlorosulphate salt Ca is coordinated to the tetrahedron of SO3Cl- group. In the film, the bond is preserved: an additional strong bond to the ether oxygen of the polymer host is observed. Consequently the chlorosulphate salt is poorly dissociated, which explains relatively low electric conductivity of the film.
