摘要 After being activated, TiFe alloys are widely concerned for their high hydrogen storage density due to their large reversible absorption and desorption capacity of hydrogen at room temperature, low price, abundant resources, moderate hydride decomposition pressure, and good hydrogen absorption and desorption kinetic performance. Meanwhile, TiFe alloys can be used as anode materials for secondary batteries, catalysts for hydrogenation, and storage media for thermal, solar, and wind energy, which has wide industrial application prospects. However, TiFe alloys have disadvantages such as difficult activation, easy toxicity, and large hysteresis. This review introduces the current research status and performance characteristics of TiFe-based hydrogen storage alloys, the phase structure, hydride phase structure, kinetic and thermodynamic models of TiFe alloys, as well as the application prospects of TiFe-based hydrogen storage alloys in practical production and the ways to improve their hydrogen storage performance, and presents the views on the future research priorities and development directions of TiFe-based hydrogen storage alloys.
