Life cycle assessment methods for BEV and PHEV batteries
 Dvořák, Matouš ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
Electromobility is a current topic and a way to reduce the carbon footprint not only in personal transport. The operation of an electric car does not have a direct impact on emissions compared to an internal combustion engine car. However, the issue remains the production of the battery, which contains rare metals that are very energy and environmentally demanding to extract. The aim of this thesis is to analyse the energy consumption and emission footprint of the production of different types of batteries. The thesis includes a general introduction to the Life Cycle Assessment (LCA) method, followed by a chapter on battery design and the classification of batteries according to electrode chemistry. The analysis of LCA studies of batteries shows that the least energy intensive battery in terms of production is the battery with NMC cathode and in terms of emissions it is the battery with LMO cathode. However, the results are strongly influenced by the input data, which are often different in LCA studies, so it is not possible to draw a clear conclusion. Part of the thesis deals with the analysis of the environmental impacts of battery production using different energy mixes and different types of production technologies. The work can serve as a basis for a more detailed investigation of the production part of the battery and for minimizing the environmental impact of this process.

Mechanical properties of materials of knee joint endoprostheses and of mechanically significant tissues in a knee joint
 Dvořák, Matouš ; Konvalinka, Jan (referee) ; Burša, Jiří (advisor)
This bachelor thesis deals with the issue of total knee endoprosthesis and describes its division in terms of its construction and attachment style. It summarizes the mechanical properties of human tissues occurring in the knee joint and simultaneously characterizes the most used materials for the production of implants. The thesis contains a calculation focusing on determining the tension around the area of contact of the tibia with the stem of the tibial component. The calculation is performed analytically and subsequently verified by the finite element method in ANSYS software.
