Workplace for measuring electrochemical potential of metals
Cápal, David ; Kazda, Tomáš (referee) ; Libich, Jiří (advisor)
This bachelor's thesis describes the issues related to corrosion in electrical engineering. Thesis describes corrosion itself, historical mentions and causes. It also deals in deatail with electrochemical corrosion and the behavior of ions at the electrode-electrolyte interface together with the redox processes that accompany them. This thesis describes the origin and use of these electrochemical reactions as a way of creating electrochemical potential in liquid electrolytes at the metal-electrolyte interface. Thesis also describes measuring methods and evaluation of measured results using polarization curves and Tafel diagrams.

Liquid electrolytes for supercapacitors
Bill, Jan ; Dvořák, Petr (referee) ; Sedlaříková, Marie (advisor)
This work deals with the preparation of liquid electrolytes from different types of aprotic solvents with the aim of their application as electrolytes in electrochemical supercapacitors. Different sorts of aprotic solvents have been chosen, in which the following forms of salts were used: LiBF4, LiClO4,LiPF6. In the next part of the work, the properties of these solvents were measured and the best electrolyte, according to the biggest possible capacity of the system, was chosen. In the theoretical part of this work, the physical principle of supercapacitors and their propeties are described. It deals with electrolytes, their division and with the properties that are appropriate for supercapacitors. The experimental part of the work describes the process of preparation of the samples of electrodes, electrolytes and the techniques of measuring their capacities.

Carbon based electrodes for supercapacitors
Moncoľ, Maroš ; Kunovjánek, Miroslav (referee) ; Dvořák, Petr (advisor)
This master thesis deals with supercapacitors based on electrical double layer and proper carbon electrodes for this type of supercapacitors. In theoretical part of work is described theory of supercapacitors, energy storage principles and their properties. In the next part are described carbon materials, their properties and electrochemical methods of measurements that we used. In the experimental part is described preparation of electrodes, results and conclusion.
