Effect of temperature on electrochemical parameters of Li-S battery
Bečan, Jan ; Skala, Kateřina (referee) ; Jaššo, Kamil (advisor)
This bachelor's thesis deals with the production of lithium-sulfur battery and the effect of changing temperatures on its electrochemical parameters. The theoretical part is focused on primary and secondary batteries and their historical evolution, anode and cathode materials for lithium-ion batteries and next-generation batteries. The practical part is focused on preparing the electrode material for lithium-sulfur battery, completion of electrochemical cell and measuring the values of cycling charge/discharge at different temperatures.

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.
