Using of X-ray for distribution analysis of electrodes for secondary cell application
 Macháč, Milan ; Bača, Petr (referee) ; Chladil, Ladislav (advisor)
This diploma thesis is focused on in-situ analysis of the composition of the negative electrodes of second secondary cells with using X-ray radiation. The first part is dedicated to the theory of lead accumulators, including charging, discharging, battery components and individual degradation mechanisms. The main part of the thesis includes the preparation of electrochemical in situ XRD cells and following measurement of the growth of lead sulphate crystals on the OCV potential. Furthermore, the lead cell was subjected to the measurement of the cyclic voltammetry around the working point of the negative electrodes. From these measurements was evident gradual increase of the lead sulfate crystals. The analysis was supplemented with electron microscopy images. In addition, were evaluated the in-situ particle analysis of the LTO Sigma sample.
