dc.description.abstractEnThe effect of the mechanical activation medium on the hydrogen absorption–desorption properties of MgH<sub>2</sub> with NiCo<sub>2</sub>O<sub>4</sub> additives is investigated. The composite 90 wt.% MgH<sub>2</sub>–10 wt.% NiCo<sub>2</sub>O<sub>4</sub> mechanically activated for 180 min under hydrogen reaches a higher absorption capacity as compared to the composite ground for the same time in an argon medium. At <i>T</i> = 573 K and <i>P</i> = 1 MPa the composite activated mechanically in a reactive medium shows a value of 5.67 wt.% while for the composite ground under argon the value is 4.36 wt.% only, both samples preserving a high absorption capacity at temperatures below 573 K. Addition of nickel cobaltite is found to have a favorable effect on the hydriding kinetics of magnesium. In order to elucidate this effect, a composite containing a large amount of NiCo<sub>2</sub>O<sub>4</sub> (50 wt.%) is also investigated.
