Infuence of Technological Parameters on Electrochemical Properties of Negative Electrode in Lithium-ion Cell
Kaňa, Michal ; Máca, Josef (referee) ; Libich, Jiří (advisor)
This diploma thesis deals with lithium-ion batteries. It is focused on negative electrode on grafit based. The goal of this thesis is to show the problematics of lithium-ion batteries together with possibilities for improvement of their basic parametres as capacity and current elektricity loadability. The first part is focused on the description of functionality of lithiumion battery. The second part is practical and it is focused on production of negative electrodes from natural graphite 280H which has different thickness and compression pressure. The third part describes preparation of negative electrodes from natural graphite 280H and also includes results of measurement. In the last part are different types of negative electrodes from natural graphite 280H compared and evaluated including the determination of conclusions. This comparison and evaluation based on obtained data.

Expanded Grpahite as Negative Electrode Material for Aporotic Intercalation Systems
Kaňa, Michal ; Čech, Ondřej (referee) ; Libich, Jiří (advisor)
This thesis deals with lithium-ion batteries. It focuses primarily on the materials which are the basis of negative electrode materials, especially on natural expanded graphite. The aim of this thesis is delineate problems of lithium-ion batteries and the possibilities how to improve their basic parameters such a capacity and current carrying capacity. The first part focuses on the description of the functionality of a lithium-ion battery. The second part focuses on the production of negative electrodes, measuring their properties and characteristics. In the last part, there are evaluated and compared individual negative electrode in the role of host of lithium and sodium ions according to the obtained data and then there are the conclusions draw
