镁基能源材料研究进展

Research Progress of Mg-Based Energy Materials

作为最轻的金属结构材料,Mg合金在轻量化方面已经得到了越来越多的应用。Mg具有较低的电极电位及储氢量较大的特点使得Mg在能源材料方面发挥越来越重要的作用。综述了Mg作为储氢材料和电池材料的研究进展,着重介绍了Mg基储氢材料的性能改善、制备方法等,同时对Mg二次电池和燃料电池体系进行了简要介绍。此外,还较详细地介绍了具有高容量储氢性能的Mg基复杂氢化物的研究现状及结果。

As the lightest metal structural material,Mg alloys have been increasingly applied in lightweighting.Owing to the lower electrode potential and higher hydrogen storage,Mg alloys can also be used in energy materials.The research of Mg alloys as hydrogen storage materials and battery materials is reviewed,focusing on the modified method and preparations of Mg-based hydrogen storage materials.In addition,applications of Mg alloys in secondary battery and fuel battery materials are also discussed.
