Influence of flame retardant on negative electrodes in lithium - ion accumulator
Buchta, Martin ; Libich, Jiří (referee) ; Máca, Josef (advisor)
This diploma thesis deals with problematics of electrochemical power sources with focus on lithium accumulators, their construction and functioning priciple. It also discusses the safety of li-ion batteries with respect to their flammability. In addition, the flame retarders, which help to lower the flammability, are listed. The thesis describes Cyclic Voltammetry and Galvanostatic Cycling with Potencial which are lithium-ion cell measuring methods. In the last part, the influence of various flame retarders on negative electrode is compared based on the conducted tests.

Development of thermal insulation materials based on natural fibers
Slípková, Andrea ; Kout, Pavel (referee) ; Zach, Jiří (advisor)
The thesis discusses possibilities of use new thermal insulation materials based on natural renewable resources (primary technical hemp) in development of the new thermal insulation materials. The main task (in the work) is to find modifications of the thermal insulation mats based on natural fibres by chemicals substances to improve the moisture properties, thermal properties and fire resistance.

Electrochemical Properties Of Gel Polymer Electrolytes Modified Flame Retardants
Veselkova, Iuliia
This paper deals with preparation of gel polymer electrolytes modified by flame retardants based on methyl methacrylate. The aim of this work was to investigate the effect of thermal polymerization method on electrochemical properties such as ionic conductivity and potential window of gel polymer electrolytes. For measuring electrochemical properties, impedance spectroscopic techniques and linear voltammetry were used. Results indicate the dependence of ionic conductivity on the amount of flame retardant.
