The Design Of Sample Holder For Xrd Measurements In Inert Atmosphere With Displacement Error Correction

Abstract

This article describes a designed of a holder for post-mortem XRD measurements of Li-ion, Na-ion and Li-S electrodes, which need to be performed in the inert atmosphere. The first part describes the measurement method and problems arising during the measurements of the samples. Subsequently, the design and construction of a new cell with hermetic insulation and sample displacement error correction possible during the operation of the diffractometer is described. Finally, the inert gas attenuation within the cell is theoretically calculated. The calculation is verified by practical measurements, and alternatives are proposed to improve the signal-to-noise ratio.
