One of the key challenges of the hydrogen economy is to develop efficient and cost-effective hydrogen storage materials. Re-Mg-Ni alloy is a potential candidate for hydrogen storage due to its high hydrogen storage capacity and good thermal stability. Moreover, the alloy also possesses excellent electrochemical properties, making it a promising material for rechargeable batteries and supercapacitors. In this study, we aim to investigate the hydrogen storage and electrochemical properties of Re-Mg-Ni alloy, and to explore its potential applications in hydrogen storage and energy conversion.Objectives:1. Synthesis of Re-Mg-Ni alloy with different composition ratios2. Characterization of the structural and morphological properties of the alloy using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS)3. Investigation of the hydrogen storage properties of the alloy through pressure-composition-temperature (PCT) measurements4. Analysis of the electrochemical properties of the alloy using cyclic voltammetry, galvanostatic charge/discharge measurements, and electrochemical impedance spectroscopy (EIS)5. Correlation of the properties of the alloy with its composition and microstructureMethodology:1.
