Abstract:

AB2 hydrogen storage alloy has attracted extensive research interest due to its advantages of high theoretical hydrogen storage capacity, long cycle life and high cost performance. However, AB2 hydrogen storage alloy has some disadvantages such as activation difficulty, toxicity and high platform, which hinders its practical application. In recent years, aiming at the defects of AB2 alloy, researchers have carried out a lot of modification studies and made great progress. This paper summarizes the research progress of AB2-type hydrogen storage alloys in the past 30 years, focuses on the methods to improve its hydrogen storage performance, and puts forward the key research directions of AB2-type alloys in the future.

Key words: AB2 type hydrogen storage alloy, Laves phase, Modification treatment
