[2L06] Hydrogen Storage Properties of Nickel-Coated Titanium Spherical Powder in the Presence of Lithium Oxide
Keywords:Tritium, lithium oxide, hydrogen absorbing alloy; metal hydrides for energy storage
A method has been proposed to produce tritium, a fuel for fusion reactors, by the nuclear reaction between neutrons and lithium in oxides in a high-temperature gas-cooled reactor, and to recover it by zirconium, a hydrogen storage alloy.
In this study, nickel was coated on the surface of the hydrogen storage alloy to prevent oxidation, and the purpose was to evaluate the hydrogen storage characteristics of the nickel-coated hydrogen storage alloy in the presence of lithium oxide (LiAlO2).
Atomized spherical titanium (Ti) powder (average particle size: 40 µm), which has a hydrogen storage capacity comparable to that of zirconium, was used as a sample.
The surface of the spherical titanium powder was successfully coated with 0.3 µm ,1.0 µm or 30 µm thick nickel by electroless wet plating method.
The initial hydrogen gas pressure was set at 2.7 x 10-2 Pa, and the hydrogen storage kinetics of Ti spherical powder and Ni coating material at 873 K were investigated from the pressure variation.
In the presentation, the effect of nickel coating on the hydrogen storage rate of spherical Ti powder in the presence of LiAlO2 will be discussed.
