Lithium-ion cell: Treatment of Natural Graphite by Lithiation Method
Bílek, Lukáš ; Kazda, Tomáš (referee) ; Libich, Jiří (advisor)
This bachelor thesis deals with the issue of lithium-ion accumulators. The thesis focuses on the negative electrode of lithium-ion accumulator made of natural graphite. In the theoretical part the thesis focuses on the characteristics, the operating principle and the use of lithium-ion accumulators. Negative electrode materials are also analyzed. The main topic of the thesis is the use of lithiation method which suppresses irreversible capacity losses with the improvement of the capacitance and current characteristics of the battery.

Dimensioning of Overhead Line Conductors According to ČSN EN 50341 and ČSN EN 50423
Dostál, Martin ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
Overhead line must be designed to be able to resist variety of influences. These influences are mechanical, which are caused by wind and rime during the normal conditions and electrical influences. Therefore all parts of overhead line have to be designed and built to withstand mechanical and electrical stress. This bachelor’s thesis is focused mainly on electrical parameters of overhead line, climatic stress and calculation of mechanical stress during limit states. There are described formulas and steps of calculation of line straining MV and HV and there are also described examples of calculation in detail.
