Study of Electrode Materials for Sodium-ion Batteries
Varmužová, Zdeňka ; Binar, Tomáš (referee) ; Libich, Jiří (advisor)
The content of this thesis is an introduction and presentation to the issue of sodium-ion batteries and a description of production of the own electrode material and its subsequent electrochemical characterization. It deals with the historical development of electrochemical sources of electrical energy from the first batteries to the current types. Study then discusses lithium-ion type batteries, which are closely related to the development of the studied sodium-ion batteries. From the point of view of sodium-ion batteries, the thesis focuses on their electrode materials, especially on anode materials based on sodium titanates. The thesis describes a synthesis of a sodium titanate and production of a negative electrode for sodium-ion battery application and construction of a test cell. The thesis then proposes and evaluates measurements verifying the properties of prepared sample of sodium titanate.

Materials and Components for Lithium-Ion Power Sources
Jirák, Tibor ; Kadlec, Jaromír (referee) ; Paidar,, Martin (referee) ; Vondrák, Jiří (advisor)
The dissertation thesis deals with electrode materials and components for lithium-ion power sources. The thesis works with two different kinds of materials, concretely nanostructured Li4Ti5O12 with spinel basis and LiCoO2 with layered structure. The electrochemical properties, structure and element analysis and utilization possibilities in electrochemical industry of new technological electrode material Li4Ti5O12 were investigated. The influences of admixtures and electrolytes on characteristics of electrode materials with aforesaid active masses were also examined. Low cost price, environmental safety and obtained results of electrochemical measurements and structure analysis refer to wide possibilities of usage electrode material Li4Ti5O12 in the field of electrochemistry.
