Study of intercalation properties of negative electrode materials
 Minda, Jozef ; Kazda, Tomáš (referee) ; Libich, Jiří (advisor)
The bachelor thesis deals with the research of intercalating properties of negative electrode materials for lithium-ion and sodium-ion accumulators. The main focus of this work is on the kinetic aspects associated with the diffusion processes of lithium in graphitic negative electrode material and sodium in titanates materials in relation to the electrochemical parameters. By comparing the materials in terms of kinetic properties expressed by the diffusion coefficient with using of electrochemical impedance spectroscopy in the state of the base material and after creating the passive layer on the electrode, it is possible to determine the application possibilities of the materials and the dependence on the electrochemical parameters. In the thesis is designed a procedure for electrodes preparation, measurement and evaluation of monitored parameters. Within the experimental part, the structural and electrochemical parameters and diffusion coefficients of the studied materials are determined by the proposed method.
