This paper describes the construction of a hermetically insulated cell for post-mortem research of electrode materials of electrochemical cells. The first part specifies the problems of XRD characterization, followed by a description of the cell solving problems with hermetic insulation and distortion of diffraction patterns. Then, a positioning system for sample displacement error correction is described and tested on the example of the Al2O3 powder standard. Finally, the measurement procedure using the constructed device on the example of a graphite electrode of the li-ion cell is shown.
