Workplace for measuring capacity and rate-capability characteristics of lithium-ion batteries
Cápal, David ; Máca, Josef (referee) ; Libich, Jiří (advisor)
This master's thesis deals with the issues of lithium-ion batteries, describing common types of commercial lithium-ion batteries, their advantages, disadvantages, and characteristic properties. The thesis focuses in more detail on the influence of temperature on the characteristics of lithium-ion battery. The thesis describes the design and construction of a workplace for measuring capacity and rate-capability characteristics of lithium-ion batteries at low and high temperatures. The thesis also describes the implementation of a cooling and heating module using a system based on Peltier devices.
Properties of low-alloyed steels at decreased temperatures
Doležal, Petr ; Pálka, Stanislav (referee) ; Záděra, Antonín (advisor)
The goal of the thesis was research in the field of structure and properties of low alloyed steels used in low temperature environment. Work was focused on heat treatment and chemical composition of the steel and their impact to hardness and impact energy values. Chemical composition and heat treatment of steel was proposed on the basis of achieved results.
