Hydrogen Storage Characteristics of Nickel Nanoparticle Coated Magnesium Prepared by Dry Particle Coating

Catalytic effect of nanoparticle 3d-transition metals on hydrogen storage properties in magnesium hydride MgH2 prepared by mechanical milling.

We examined the catalytic effect of nanoparticle 3d-transition metals on hydrogen desorption (HD) properties of MgH(2) prepared by mechanical ball milling method. All the MgH(2) composites prepared by adding a small amount of nanoparticle Fe(nano), Co(nano), Ni(nano), and Cu(nano) metals and by ball milling for 2 h showed much better HD properties than the pure ball-milled MgH(2) itself. In par...

Improvement of humidity resistance of magnesium powder using dry particle coating

Dry particle coating is used to enhance the moisture resistance of ground magnesium powder (primary size 75 Am) by coating its surface with carnuba wax (primary size 15 Am). Coating was done using magnetically assisted impact coating (MAIC), and two high-speed impaction-coating devices, the hybridizer and mechanofusion. The uncoated and coated samples are characterized by scanning electron micr...

The Effect of Palladium Coating on Hydrogen Storage Alloy Electrodes for Nickel/Metal Hydride Batteries

Este trabalho apresenta estudos de carga/descarga realizados sobre ligas metálicas multi componentes (“misch metal al loys”) recobertas com Paládio e que podem ser utilizadas como eletrodos em baterias de níquel/hidreto metálico. Foi determinado o efeito do recobrimento nas características voltamétricas, no ciclos de vida e na capacidade sob diversos re gimes de descarga para os eletrodos de li...
