Abstract : A study has been performed on the association and molecular dynamics of alkali-ion salts, especially lithium salts dissolved in acyclic polyethers. The purpose of the study was to investigate the status of the electrolyte in these media, the lifetime of the species in solution and their molecular dynamics. Several techniques such as electrical conductance, infrared spectra, ultrasonic relaxation kinetics, microwave and infrared dielectric relaxation and molar refractometry have been used for the above research. The subject of this study is highly relevant for the construction of lithium batteries using polymer electrolyte media. Four published papers, and three more in preparation, have resulted from this project.
