High hydrogen absorption and desorption rates are two of significant index parameters for the applications of hydrogen storage tanks. Analysis of the hydrogen absorption and desorption behaviours by the isothermal kinetic models is an efficient way to investigate the kinetic mechanism. Multitudinous kinetic models have been developed to describe the kinetic processes. However, these kinetic models were deduced based on some assumptions and only appropriate for the specific kinetic measurement methods and rate-controlling steps, which is sometimes confusing for application. The kinetic analysis procedures using those kinetic models, as well as the key kinetic parameters, are not clear for many researchers who do not become familiar with this field. These problems will prevent kinetic models and their analysis methods from revealing the kinetic mechanism of hydrogen storage alloys. Thus, this review mainly focuses on the summarisation of the kinetic models based on the different kinetic measurement methods and rate-controlling steps, and the introduction of the analysis procedures and the applications of kinetic models in metal hydrides.
