摘要：

The density, the propagation rate of ultrasound, the electroconductivity, and the viscosity of lithium hexafluoroarsenate solutions in tetrahydrofuran, which are perspective liquid-phase components for the creation of novel polymer electrolytes for chemical lithium power sources, are determined. The ionic association is investigated on the basis of the Lee-Wheaton model. The determination of the solvation numbers in the region of concentrations that are in reality applied in the lithium power sources is conducted on the basis of the method of isoentropy compression. It is shown that the phenomenon of anomalous electroconductivity of the system under test may be connected with an ionotropic electroconduction mechanism.
