Mg-Based Thin Films as Model Systems in the Search for Optimal Hydrogen Storage Materials

The kinetics of lightweight solid-state hydrogen storage materials: A review

“…If hydrogen diffuses rapidly through the grain boundary, then a new and smaller grain size with higher defect densities will improve the rates of hydrogen absorption and desorption. This technique does not always have the desired outcome; however, there is good experimental evidence from previous studies that milling and alloying enhance the hydrogen storage properties [125]. All of these nanostructuring techniques, which are discussed in the following sections, provide several advantages and improvements regarding the hydrogen kinetics properties of lightweight metal-based materials.…”
