Analysis of the hydrogenation and dehydrogenation behaviors by kinetic models is an efficient approach to the in-depth understanding of the kinetic mechanism for hydrogen storage materials. A large number of kinetic models as well as analysis methods based on these models have been extensively applied in hydrogen storage materials, and kinetic parameters with physical interpretations are determined to reveal the kinetic mechanism of hydrogenation and dehydrogenation reactions. However, the assumptions and derivation steps of these models are usually difficult to find, and the selection of analysis methods is sometimes confusing. Moreover, some recently proposed models and analysis methods have not been introduced to investigate the kinetic mechanism of hydrogen storage materials yet. These problems significantly prevent the kinetic models as well as analysis methods from further revealing the kinetic mechanism for hydrogen storage materials. Therefore, this review mainly focuses on the illustration of the assumptions and derivation steps of the kinetic models, summarization of corresponding analysis methods, and introduction of some recently proposed kinetic models and analysis methods for hydrogen storage materials.
