Description

Density, speed of ultrasonic wave propagation, electric conductivity and viscosity of LiAsF6 solutions in tetrahydrofuran being available liquid-phase components for the creation of new polymer electrolytes for lithium chemical current sources are determined. Ionic association of the LiAsF6-tetrahydrofuran system is studied on the basis the Lee-Wheaton model. Determination of solvation numbers in the field of concentrations substantively applied in lithium current sources was conducted by the isoentropy compression method. Event of anomalous electric conductivity of the studied system is demonstrated to be connected with the ionotropic mechanism of electric conductivity

Abstract (Russian)

Определены плотность, скорость распространения ультразвука, электропроводность и вязкость растворов LiAsF6 в тетрагидрофуране, являющихся перспективными жидкофазными компонентами для создания новых полимерных электролитов для литиевых химических источников тока. На основе модели Ли-Уитона исследована ионная ассоциация системы LiAsF6-тетрагидрофуран. Методом изоэнтропийного сжатия проведено определение чисел сольватации в области концентраций, реально применяемых в литиевых источниках тока. Показано, что явление аномальной электропроводности исследуемой системы может быть связано с ионотропным механизмом электропроводности
