What is Evaluation of Enthalpy Change Due to Hydrogen Desorption for Lithium Amide/imide System by Differential Scanning Calorimetry about?
Enthalpy change ( H) due to hydrogen desorption (H-desorption) for the lithium amide/imide system was evaluated by differential scanning calorimetry (DSC) measurement. In order to obtain the accurate and precise value of H, we have paid special attention to following two points for correcting raw experimental data. One is to determine a cell constant of DSC equipment, which was evaluated by using the TiO 2 -doped MgH 2 compound as a reference because of its quite similar hydrogen desorption properties to that of the lithium amide/imide system. The other is to estimate the sample amount corresponding to the H-desorption reaction from weight loss in the thermogravimetric (TG) analysis. By performing both the corrections, the H value due to the H-desorption reaction from LiNH 2 + LiH to Li 2 NH + H 2 was evaluated to be 67 kJ/mol H 2 .
