The relationship between discharge capacity of LaNi5 type hydrogen storage alloys and formation enthalpy

Improvement in the low-temperature performance of AB5 metal hydride alloys by Fe-addition

“…to the maximum capacity as proposed by Ma et al [60]. The driving forces from large unit cell and hyper-stoichiometry must be about the same, and therefore the net change resulting from Feaddition is small.…”

Comparisons of metallic clusters imbedded in the surface oxide of AB2, AB5, and A2B7 alloys

“…The Misch-metal based AB 5 hydrogen storage alloy is the conventional choice for metal hydride (MH) electrode material used in nickel metal hydride (Ni/MH) batteries [1][2][3][4][5][6][7]. However, the limited discharge capacity of this alloy has prompted a search for alternative materials with higher hydrogen storage capacities.…”

Sustainability applications of rare earths from metallurgy, magnetism, catalysis, luminescence to future electrochemical pseudocapacitance energy storage

“…Doping, synthesis of sub-stable phases, and altering the reaction path, for instance, can effectively reduce the enthalpy of generation; however, not all reactions are totally reversible, resulting in a lower hydrogen storage capacity. 163 Although rare earths still face serious challenges in the practical application of hydrogen storage, they offer a new idea in the development of hydrogen storage materials.…”
