摘要
TiFe合金作为一种传统的储氢材料,因其分解压力适中,储氢量较大,原材料储量丰富而引起广泛的研究兴趣。但是该合金存在活化困难、易中毒和滞后大等缺点,严重阻碍了其实际应用。针对TiFe合金的缺点研究者们进行了大量的改性研究。综述了TiFe系储氢合金的研究进展,介绍了改善其储氢性能的方法及其优缺点,并展望了TiFe系合金今后的研究方向和重点。
As a traditional hydrogen storage alloy, TiFe based hydrogen storage alloy has attracted wide atten tion due to its moderate desorption pressure, relatively high hydrogen storage capacity and abundant resources. Howe- ver, the industrial application of TiFe alloy is hindered because of its poor activation characteristic, susceptibility to impurities in hydrogen and large hysteresis. In the past years, great efforts have been made to overcome these draw- backs of TiFe alloy. In this article, the research advances in improving hydrogen storage performances of TiFe-based alloy are reviewed, and the advantages and disadvantages of the methods for the improvement are summarized. The prospects of future research and development of TiFe-based alloy are also discussed.
