Liquid electrolytes for lithium-ion accumulators
Štichová, Zuzana ; Vondrák, Jiří (referee) ; Sedlaříková, Marie (advisor)
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.

Electrolytes containing a phosphorus-based flame retardant
Pelikán, Ondřej ; Libich, Jiří (referee) ; Máca, Josef (advisor)
The diploma thesis is focused on the theoretical knowledge of lithium accumulators. More attention is given to electrolytes and especially to flame retardants, where the types and individual examples of flame retardants are described more detailed. The practical part is focused on the individual laboratory measurement of selected samples of electrolytes with different flame retardants. The measurement results are analyzed in other parts.
