摘　　要：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 AB_(5)-,AB_(2)-and ABtype 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.
