Electrochemical preparation of graphene oxide and its utilization in LiFePO4 composites
 Krejčí, Pavel ; Chladil, Ladislav (referee) ; Čech, Ondřej (advisor)
This work deals with issues of application of the graphene material in the field of electrochemical energy storage. It includes basic graphene properties, the overview of methods for the production of lithium-iron-phosphate/graphene composites and results of different research approaches. The general aim is to present growing opportunity of application of graphene based composites in the electrochemical energy storage field. In the experimental part of this work, a electrochemical exfoliation of graphite and a production of LFP/G composites with different amount of graphene material and with different types of graphene material are carried out. This work includes also x-ray diffraction spectroscopy measurements and the evaluation of impacts of graphene additives on final properties of the electrochemical energy storage.

Study Of Electrochemical Properties Of Gel Polymer Electrolyte Based On Tetraethyl Ammonium Salt
 Veselkova, Iuliia
In this study, gel polymer electrolytes based on tetraethyl ammonium tetrafluoroborate salt (TEA BF4) were prepared by UV-light polymerization technique. The effect of adding TEA BF4 in different concentrations on electrochemical and mechanical properties were studied. Ionic conductivity and potential window were measured by impedance spectroscopy and linear voltammetry methods. The results indicate how salt concentration affects electrochemical properties of gel polymer electrolytes.
