Thermodynamic characterization and statistical thermodynamics of the TiCrMn–H2(D2) system

Advanced high-pressure metal hydride fabricated via Ti–Cr–Mn alloys for hybrid tank

“…In TieZreCreMn Laves phase alloys, Park et al [22] also observed that the lattice parameter and hydrogen capacity increased, while the decomposition plateau decreased when Ti was substituted by larger Zr atoms. Beeri et al [23] partially substituted some Cr by Mn to form TiCrMn alloy, the DH d has been decreased to 19.6 kJ/mol H 2 , which was close to the target value of high-pressure alloy (20 kJ/mol H 2 ). Compared with these stoichiometric AB 2 alloys, non-stoichiometric alloys usually exhibited improved hydrogen storage properties due to the introduction of disorder in an unchanged C14 hexagonal structure presenting modified cell parameters the presence of excess elements [24,25].…”

Development of metal hydride with high dissociation pressure

“…Ti Cr Mn hydride is a useful metal hydride with high dissociation pressure. However, very few studies have been reported on the hydrogen absorption and desorption properties of Ti Cr Mn at high-pressure above 10 MPa [30][31][32].…”

Thermodynamic and Kinetic Properties of La20.5MgNi78.5 and La15.5Mg6Ni78.5 Hydrogen Storage Alloys: The Theoretical Models and Their Verifications

“…Assuming that the metal-hydrogen system was univariant, Lacher et al [13] interpreted the PCI curve of Pd-H system. Later, Beeri et al [14][15][16] revised the Lacher-type model by applying Bragg-Williams and the Quasi-Chemical approximations and derived the PCI curves, considering the situations of real gas and the existence of multiple plateaus. Senoh et al [17] interpreted the PCI curves theoretically based on statistical mechanics, in which the RNi 5 (R = La, Pr, Nd and Sm)-H was regarded as a grand canonical ensemble.…”
