“…Studies on superlattice alloys began with the structure [9] and gaseous phase (GP) H-storage characteristics of the single rare earth element (RE)-based AB 3 alloys [10][11][12] and soon shifted to the Mm-based A 2 B 7 chemistry for battery applications [13][14][15][16]. Some researchers continued to work on RE-based AB 3 chemistry for its basic electrochemical (EC) properties [17][18][19][20][21][22]. In the meantime, RE-based A 5 B 19 was also highly promoted for battery applications [23][24][25][26][27].…”

Abstract:The effects of seven constituent phases-CeNi 3 , NdNi 3 , Nd 2 Ni 7 , Pr 2 Ni 7 , Sm 5 Ni 19 , Nd 5 Co 19 , and CaCu 5 -on the gaseous phase and electrochemical characteristics of a superlattice metal hydride alloy made by induction melting with a composition of Sm 14 La 5.7 Mg 4.0 Ni 73 Al 3.3 were studied through a series of annealing experiments. With an increase in annealing temperature, the abundance of non-superlattice CaCu 5 phase first decreases and then increases, which is opposite to the phase abundance evolution of Nd 2 Ni 7 -the phase with the best electrochemical performance. The optimal annealing condition for the composition in this study is 920 • C for 5 h. Extensive correlation studies reveal that the A 2 B 7 phase demonstrates higher gaseous phase hydrogen storage and electrochemical discharge capacities and better battery performance in high-rate dischargeability, charge retention, and cycle life. Moreover, the hexagonal stacking structure is found to be more favorable than the rhombohedral structure.

“…Many scholars study high-capacity alloys with AB 3 components (A: RE metals, Mg, Ca, etc. ; B: transition metals) [101][102][103]. Most scholars synthesize AB 3 alloy by melting method, but MA also has unique advantages in synthesizing AB 3 alloy.…”

Hydrogen energy is a very attractive option in dealing with the existing energy crisis. For the development of a hydrogen energy economy, hydrogen storage technology must be improved to over the storage limitations. Compared with traditional hydrogen storage technology, the prospect of hydrogen storage materials is broader. Among all types of hydrogen storage materials, solid hydrogen storage materials are most promising and have the most safety security. Solid hydrogen storage materials include high surface area physical adsorption materials and interstitial and non-interstitial hydrides. Among them, interstitial hydrides, also called intermetallic hydrides, are hydrides formed by transition metals or their alloys. The main alloy types are A2B, AB, AB2, AB3, A2B7, AB5, and BCC. A is a hydride that easily forms metal (such as Ti, V, Zr, and Y), while B is a non-hydride forming metal (such as Cr, Mn, and Fe). The development of intermetallic compounds as hydrogen storage materials is very attractive because their volumetric capacity is much higher (80–160 kgH2m−3) than the gaseous storage method and the liquid storage method in a cryogenic tank (40 and 71 kgH2m−3). Additionally, for hydrogen absorption and desorption reactions, the environmental requirements are lower than that of physical adsorption materials (ultra-low temperature) and the simplicity of the procedure is higher than that of non-interstitial hydrogen storage materials (multiple steps and a complex catalyst). In addition, there are abundant raw materials and diverse ingredients. For the synthesis and optimization of intermetallic compounds, in addition to traditional melting methods, mechanical alloying is a very important synthesis method, which has a unique synthesis mechanism and advantages. This review focuses on the application of mechanical alloying methods in the field of solid hydrogen storage materials.

The power consumption has increased enormously due to the intervention of high end technology and it is necessary to meet this power demand. The power pushed into any electrical system should be highly reliable, secured with sufficient quantity and quality. One such solution is to bring reliable and flexible power by introducing Hybrid energy systems into the network. The main motivation of hybrid energy systems is to improve the delivery of power at the utilities and customer end. In this paper, a complete literature review is made on the integration of solar photovoltaic, wind and diesel generator with energy storage systems like hydrogen based fuel cells and batteries. This hybrid system reduces the operating time of diesel generator, save the fuel consumption and hence accomplishes the peak demand with diesel generator.
