Neste trabalho, os efeitos do tratamento termico nas estruturas e propriedades eletroquimicas de ligas para armazenamento de hidrogenio Mg 0.9 Ti 0.1 Ni foram investigadas em detalhe. As analises por difracao de raios-X (XRD) e microscopia eletronica (SEM) mostraram que as amostras exibiram predominantemente uma estrutura amorfa. Estudos eletroquimicos revelaram que o tratamento termico pode melhorar a capacidade maxima de descarga e ciclabilidade dos eletrodos desta liga. O valor de C max a liga Mg 0.9 Ti 0.1 Ni preparada por moagem, foi de apenas 229,9 mAh g -1 ; entretanto, o valor atingiu 331,9 mAh g -1 apos o tratamento termico a 873K por 8 h seguido de moagem. A voltametria ciclica, espectroscopia de impedância eletroquimica e polarizacao potenciodinâmica indicaram que o tratamento termico nao so aumentou a capacidade de descarga, mas tambem melhorou a cinetica de carga/descarga da liga Mg 0.9 Ti 0.1 Ni. In the present study, the effects of heat treatment on the structures and electrochemical properties of Mg 0.9 Ti 0.1 Ni hydrogen storage alloys have been investigated in detail. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses showed that the samples exhibited a predominantly amorphous structure. Electrochemical investigations revealed that heat treatment can improve the maximum discharge capacity and cyclic stability of the alloy electrodes. For Mg 0.9 Ti 0.1 Ni alloy prepare by ball milling, the value of C max was only 229.9 mAh g -1 , however, the value reached 331.9 mAh g -1 after heat treatment at 873K for 8 h and then milling. The cycle voltammetry, electrochemical impedance spectroscopy and potentiodynamic polarization indicated that heat treatment not only increased the discharge capacity but also improved the charge/discharge kinetics of Mg 0.9 Ti 0.1 Ni alloy.
