Study of electrode materials for post-lithium ion systems
Kekelák, Miroslav ; Jaššo, Kamil (referee) ; Kazda, Tomáš (advisor)
This bachelor thesis deals with studying electrode materials for post-lithium ion systems. The theoretical part describes the principle, history and construction of lithium-ion battery cells. A separate chapter is dedicated to the materials of positive and negative electrodes for lithium-ion batteries. The third chapter is dedicated to the principles of new generation lithium-air and sodium-ion batteries. The last chapter of theoretical part is dedicated to lithium-sulfur batteries, which describes their principle, history, used electrode materials and the influence of binders. The experimental part is dedicated to the preparation of the electrode material of lithium-sulfur accumulator in combination with water-soluble binders and their measurement using electrochemical methods.

Effect of compaction pressure to the electrochemical properties of the electrodes for Li-S accumulators
Jaššo, Kamil ; Tichý, Jiří (referee) ; Kazda, Tomáš (advisor)
The purpose of this diploma thesis is to describe the impact of compaction pressure on the electrochemical parameters of lithium-sulfur batteries. Theoretical part of this thesis contains briefly described terminology and general issues of batteries and their division. Every kind of battery is provided with a closer description of a specific battery type. A separate chapter is dedicated to lithium cells, mainly lithium-ion batteries. Considering various composition of lithium-ion batteries, this chapter deeply analyzes mostly used active materials of electrodes, used electrolytes and separators. Considering that the electrochemical principle of Li-S and Li-O batteries is different to Li-ion batteries, these accumulators of new generation are included in individual subhead. In the experimental part of this thesis are described methods used to measure electrochemical parameters of Li-S batteries. Next chapter contains description of preparing individual electrodes and their composition. Rest of the experimental part of my thesis is dedicated to the description of individual experiments and achieved results.
