Synthesis and characterization of sulfurized polymers for electrochemical power sources
 Svoboda, Lukáš ; Kazda, Tomáš (referee) ; Čech, Ondřej (advisor)
Batteries based on lithium-sulfur technology have the potential to increase the amount of stored energy in comparison with current lithium-ion systems while maintaining the same weight. Achieving this goal is possible due to the high theoretical energy density of sulfur, which exceeds the values of other materials used in batteries. However, these batteries suffer from several failing, which still hinder the practical use. The use of amorphous sulfur instead of its crystalline form might lead to increasing of durability and charge efficiency. Inverse vulcanization of sulfur seems to be the perspective method for the preparation of polymer sulfur because it prevents its recrystallization and stabilizes amorphous sulfur. The aim of this thesis is the preparation and study of properties of materials made of inverse vulcanized sulfur.

Synthesis, Characterization And Centrifugal Force Spinning Of Sulfurized Polymers For Electrochemical Power Sources
 Svoboda, Lukáš
Lithium-sulphur batteries have the potential to increase battery capacity while maintaining their weight and volume. This is possible due to the high theoretical energy density of sulphur. However these batteries suffer from several failing, which still hinder practical use. The use of amorphous sulphur instead of its crystalline form leads to increasing of cyclic stability and charge efficiency. Inverse vulcanization of sulphur seems to be perspective method for the preparation of polymer sulphur, because it prevents its recrystallization and stabilizes amorphous sulphur.
