Resumen
In this article the results of the negative electrode performance produced by
La0.7Mg0.3Al0.3Mn0.4Co0.5Ni3.8 as-cast alloy adding 1 to 10% of carbon nanotube (CNT) or reduced
graphene oxide (rGO) were investigated as Ni-MH batteries. 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.
