چکیده انگلیسی
Ball milling of the LiNH2 + LiH storage system was performed at 20 °C, â40 °C, and â196 °C, and the resulting powders were analyzed using X-ray diffraction, scanning electron microscopy, nuclear magnetic resonance (NMR), specific surface area analysis, and kinetics cycling measurements. Ball milling at â40 °C showed no appreciable deviations from the 20 °C sample, but the â196 °C powder exhibited a significant increase in the hydrogen desorption kinetics. NMR analysis indicates that a possible explanation for the kinetics increase is the retention of internal defects generated during the milling process that are annealed at the collision site at higher milling temperatures.
