The materials under investigation are potential candidates as electrode active materials for Mg-ion batteries. It is of paramount importance to have a deep structural characterization of this material and in particular the reactivity of this material with potential electrolytes. It is necessary to know the side reactions to better understand the chemistry behind it to improve the material. The key objective sought from this experiment is the identification of MgH2 in the material. It is known by some previous experiments that hydrid is likely to form due to the material reacting with the electrolyte. Due to the low x-ray scattering power of MgH2, neutron diffraction becomes an essential tool in order to get a complete picture of the materials and identify whether MgH2 remains in the material or not.
