Hydrogen storage properties of new ternary alloys: PrMg2Ni9 and PrMgNi4

The hydrogen storage properties of the new ternary alloys, PrMg2Ni9 and PrMgNi4, were investigated. The electrode properties of REMgNi4 alloys were measured by means of simulated battery test. The results indicate that all the negative electrodes of the alloys showed a good cycle life, and the amorphous PrMgNi4 has a good discharge capacity.
