Present thesis explores the mechanical and ceramic synthesis of A2MnO2F compounds with face cubic centered (fcc) structure. In which A stands for Na and Li. The synthesis was performed using different reactants and optimized by the process of changing two parameters: temperature and time. In addition to the synthesis, the characterization of the synthesized material was carried out. Characterization was carried out using various analytical methods such as: X-ray diffraction (XRD), Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX), Nuclear magnetic resonance (NMR), Transmission electron microscopy (TEM) and Inductively coupled plasma with mass spectrometry (ICP-MS). As part of the characterization, the electrochemical behavior of the material was also tested using swagelock cells. The results show that temperature and time influence the course of the reaction. With higher temperature and longer time, the reaction is more complete. Success of the synthesis, to get the desired product is also influenced by reactants and the synthesis method. In the case of sodium, in both methods of synthesis we were not able to synthesize the product, while in the case of lithium, the desired product was obtained by mechanical synthesis.
