Abstract
Storage of hydrogen in solid-state materials offers a safer and compacter way compared to compressed and liquid hydrogen. Vanadium (V)-based alloys attract wide attention, owing to the total hydrogen storage capacity of 3.8 wt% and reversible capacity above 2.0 wt% at ambient conditions, surpassing the AB5-, AB2- and AB-type hydrogen storage alloys. However, several challenges, such as insufficient capacity, cyclic stability and high raw material costs, hinder the practical applications of V-based alloys. This review provides an overview of the recent advances in hydrogen storage properties of V-based alloys. The mechanism and optimization strategies of hydrogen storage properties and cyclic stability are discussed in detail, and furthermore, the approaches to reduce manufacturing costs are compared comprehensively.
与压缩氢和液态氢相比，在固态材料中储存氢是一种更安全、更紧凑的方法。由于钒（V）基合金在环境条件下的总储氢能力达到 3.8 wt%，可逆储氢能力超过 2.0 wt%，超过 AB5、AB2 和 AB 型储氢合金，因此受到广泛关注。然而，容量不足、循环稳定性和原材料成本高等挑战阻碍了 V 基合金的实际应用。本综述概述了 V 基合金储氢性能的最新进展。文中详细讨论了储氢性能和循环稳定性的机理和优化策略，并对降低制造成本的方法进行了综合比较。
