The hydrogen absorption–desorption characteristics of the nanocomposites 90 wt.% Mg2Ni–10 wt.% C (graphite) and 75 wt.% Mg–15 wt.% Mg2Ni–10 wt.% C obtained by mechanical alloying have been investigated. Modification with graphite has been found to improve the hydriding kinetics of Mg2Ni at a temperature of 573 K and below. The composite 75 wt.% Mg–15 wt.% Mg2Ni–10 wt.% C has a high hydrogen absorption capacity and is characterised by very good kinetic parameters of hydriding at 473 and 423 K...< Réduire
