Research Progress in V Based Hydrogen Storage Alloys

介绍了近几年V基贮氢合金的研究进展。总结出V基合金具有如下特点:室温有效吸氢量可达2.4wt%以上,吸放氢循环性能优良,室温平台压力可达几个大气压,放氢效率不高,成本较高,但有可能通过利用廉价钒铁原料制备合金的方式降低成本。同时,提出了后续研发重点。

Research progress in V based hydrogen storage alloys in recent years is introduced. Some characteristics are concluded, The effective hydrogen absoption content at ambient temperature is over 2. 4wt%. The cyclic property of hydrogen absorption and desorption is favorable. The plateau pressure at ambient temperature can reach to a few of atmospheres. While the V based alloys has low hydrogen desorption efficiency and high cost, it＇s possible to reduce the cost by using low-cost vanadium iron to prepare alloys. The key technologies for future research in V based hydrogen storage alloys development are proposed.
