Aluminum hydride (AlH₃) is a binary metal hydride that contains more than 10.1 wt% of hydrogen and possesses a high volumetric hydrogen density of 148 kg H₂ m⁻³. Pristine AlH₃ can readily release hydrogen at a moderate temperature below 200 °C. Such high hydrogen density and low desorption temperature make AlH₃ one of most promising hydrogen storage media for mobile application. This review covers the research activity on the structures, synthesis, decomposition thermodynamics and kinetics, regeneration and application validation of AlH₃ over the past decades. Finally, the future research directions of AlH₃ as a hydrogen storage material will be revealed.

氢化铝（AlH ₃）是一种二元金属氢化物，其包含大于10.1重量％的氢并且具有148kg H ₂ m ^-3的高体积氢密度。原始AlH ₃可以在低于200°C的中等温度下轻松释放氢。如此高的氢密度和低的解吸温度使AlH ₃成为移动应用中最有希望的储氢介质之一。这篇综述涵盖了过去几十年中有关AlH ₃的结构，合成，分解热力学和动力学，再生和应用验证的研究活动。最后，将揭示AlH ₃作为储氢材料的未来研究方向。
