Technologies for storing electrical energy in electric vehicles
Zdražil, Marek ; Walek, Agata (oponent) ; Langerová, Petra (vedoucí práce)
This bachelors thesis is focused on technologies used for storing electric energy in electric vehicles. The first chapter deals with history of technologies for electric energy storing and their use in early electric vehicles. It continues by description of electric vehicles that were occasionally produced through the 20th century, up to 1990s when this technology became attractive again. The following chapter describes types of electric cars and gives us examples of currently produced cars. The third part deals with technologies used in present and recent past. Subsequently, in the last chapter, there are introduced technologies which might be sufficient substitution to current systems or even to conventional combustion engines in future.
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.
