Impact of technological parameters on electrochemical properties of negative electrode in lithium-ion battery
Živčic, Samuel ; Máca, Josef (referee) ; Libich, Jiří (advisor)
This bachelor thesis deals with the issue of li-ion batteries and consists of two main parts. The first part of the thesis deals with a theory. It describes the functionality of electrochemical cells, especially li-ion cells. Operational principle of the cell is discussed, with the main focus given on negative electrode (anode) and the material it consists of, the natural graphite, mainly his electrochemical properties. Last chapter of theory describes expected impact of technological parameters on electrochemical properties of negative electrode. The second part of the thesis is the practical part. First, it describes procedure of making electrodes in laboratory and afterwards it provides an explanation of used measuring methods, steps taken during the measurement, and the results of the measurements. At the end of the thesis, the influence of pressure and layer thickness on electrochemical properties of natural graphite and on capacitive and current characteristics of negative electrode is evaluated.
