The as cast alloy were investigated with X-ray diffraction (XRD) and scanning electron microscopy (SEM). The CNT and rGO were characterized by high resolution SEM-FEG. The discharge capacity obtained during the electrochemical characterization showed that in the addition of 1% rGO the discharge capacity was 332 mAh and 1% CNT 364 mAh , being that the rGO batteries maintaining better cyclic stability during the electrochemical test.153-157closedAccesshydrogen storagehydrideselectrodesmetalselectrochemistrychemical propertiesArtigo de periódico101210.4028/www.scientific.net/MSF.1012.153Sem Percentil15.00
