Among them, alloys have become leading hydrogen-storage materials owing to their favorable cost, safety, operating conditions, particularly their high energy density by volume. For example, the most commonly used commercial hydrogen-storage alloy in nickel–metal hydride batteries is the AB 5 alloy with a CaCu 5 crystal structure.
In recent years, high-entropy alloys (HEAs) have been extensively applied to structural and functional materials owing to their unique physical and chemical properties. Therefore, HEAs have emerged as a promising materials. This review summarizes recent research progress on HEAs for hydrogen storage.
High-energy-density hydrogen-storage technology is essential to bridge the gap between hydrogen production and its energy-storage applications. At the same time, hydrogen is a flammable and explosive gas: when the concentration of hydrogen in air is 4.1–75 vol% , it will explode in case of fire.
Alloys, such as cobalt alloys with boron, phosphorus, and silicon, have been studied for their hydrogen storage capacity and electrochemical properties. Among multiple studied, the Ti2Ni alloy shows good hydrogen storage capacity and discharge efficiency when synthesized by induction melting method.
The results of this study indicate that HEAs are potential hydrogen-storage materials; however, additional research and improvements are required to enhance their hydrogen storage/release rate and cycle stability. HEAs are anticipated to become increasingly important in hydrogen energy storage and transportation in the future.
