Metal hydrides storage are used for safe storage and portable hydrogen over long periods.
Metal hydrides are materials capable of absorbing and releasing hydrogen, allowing hydrogen to be stored more safely and at a higher density than liquid hydrogen, and are employed as stationary storage tanks.
Nickel–metal hydride (NiMH) batteries based on such materials combine safety with high energy density, and are widely used in hybrid vehicles.
At present, the most advanced negative electrode material is the La–Mg–Ni-based superlattice alloy that we have developed; however, we are also pursuing research on ternary metal hydrides for further performance enhancement, as well as the development of next-generation hydrogen rechargeable batteries.
