Abstract: [slo] [eng]
Cieľom tejto diplomovej práce bolo meranie elektrickej vodivosti a dynamickej viskozity elektrolytov. Na základe týchto meraní bolo možné overiť Waldenov vzťah medzi meranými veličinami. Boli použité elektrolyty na bázy sulfolanu v kombinácií s propylenkarbonátom a so soľou. Diplomová práca sa tiež zaoberá meraním dielektrických vlastností elektrickou metódou a optickou metódou pomocou refraktometrie. Taktiež boli stanovené body tuhnutia zmesi sulfolanu a propylenkarbonátu pomocou kryoskopie. The aim of this master´s thesis was the measurement of electrical conductivity and dynamic viscosity of the electrolytes. Based on these measurements to verify Walden theorem between measured variables. Electrolytes were used on sulfolane base in combination with propylene carbonate and salt. The thesis also deals with the measuring method of dielectric properties of electrical and optical method with a refractometer. The freezing point of combination of sulfolan and propylene carbonate were determined by cryoscopy.
Keywords: conductivity; freezing point; liquid electrolyte; lithium-ion accumulator; permittivity; propylene carbonate; refractive index; sulfolane; viscosity; Walden theorem
