A structure study of high-voltage cathode materials for lithium ion battery using X-ray crystallography
Kunický, Daniel ; Čech, Ondřej (referee) ; Chladil, Ladislav (advisor)
This diploma thesis deals with the X-Ray crystallography study of structural changes within lithium-ion cells. First part consists of the theoretical discussion about the structural changes in commerce lithium-ion cells with focus on X-Ray crystallography. Then the ex situ, in situ and operando terms are discussed. Verification of the XRD usage is realized on the LiFePO4 material. Experimental part deals with the optimization and preparation of electrochemical cells and the measurements. Finally, results of the Rietveld analysis are discussed.
