LOPEZ-BAEZ, I.; ESPINOZA-BELTRAN, F.J.  e  BARREIRO-RODRIGUEZ, G.. Desarrollo de un nanomaterial base TiFe, como electrodo para baterías recargables tipo NiMH, obtenido por aleado mecánico de alta energía. Rev. mex. fis. [online]. 2006, vol.52, n.3, pp.278-284. ISSN 0035-001X.

In this work the development of electrodes type A-B (A: Ti; B: Fe, Co, Ni) is presented starting from nanostructured alloys for rechargeable batteries also secondary calls. The purpose of the employment of a metallic alloy in form of nanometric powder like electrode is that its great surface allows making more efficient the electrochemical processes. The methodology that is used for the development of these materials consists in: to use the high energy mechanic alloying, because it is very practical and we can obtain a grain size of nanometric order in relatively short times; to examine their physiochemical characteristic (morphology, composition); to determine the Hydrogen absorption/desorption behavior; and to evaluate their yield characteristics like hydride electrodes in an electrolytic cell.
