Abstract
Ball milling of the LiNH(2) + LiH storage system was performed at 20 degrees C, -40 degrees C, and -196 degrees 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 -40 degrees C showed no appreciable deviations from the 20 degrees C sample, but the -196 degrees 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.
