Artigo IPEN-doc 27603 The influence of the addition of rGO and CNT on the electrochemical properties of the batteries the LaNi-based battery alloys2020 - SOARES, E.P.; FILHO, J.C.S.; CASINI, J.C.S.; FARIA, R.N.; TAKIISHI, H.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.Resumo IPEN-doc 25315 The influence of the addition of rGO and CNT on the electrochemical properties of the batteries the LaNi-Based Battery Alloys2018 - SOARES, E.P.; CASINI, J.S.; FARIA, R.N.; SILVA FILHO, J.C.; TAKIISHI, H.In this article the results of the investigation are reported where batteries were made from the negative electrodes of the alloy La0.7Mg0.3Al0.3Mn0.4Co0.5Ni3,8, without annealing, adding 0, 1, 2, 5, 10% , both for carbon nanotube (CNT) and for reduced graphene oxide (rGO) where 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. The addition materials CNT and rGO were characterized by high resolution MEV-FEV - Field emission gun.
