The Effect of Palladium Coating on Hydrogen Storage Alloy Electrodes for Nickel/Metal Hydride Batteries
نویسنده
چکیده
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 liga metálica. O número de ciclos necessários para ativar os eletrodos de liga metálica diminui quando o conteúdo de Pd aumenta. Os resultados mostram também que as ligas recobertas com Pd apresentam uma maior capacidade de carga e um desempenho melhor que aquelas sem o Pd. Essas melhores características podem ser atribuídas ao efeito catalítico do Pd sobre a reação de hidrogênio..

متن کاملPERFORMANCE OF AB, ALLOYS FOR HYDROGEN STORAGE AND HYDRIDE ELECTRODES
Two types of hydride electxodes are potential candidates to replace the Cd elecsode in NilCd batteries, One is of the A type where A is a rare earth metal or mixture thereof, and B is the transition metal. The other is commonly referred to as A type. A , type alloys with partial substitution of the B element in A type hydride material (Ovonic) with Co, Mn, Al, and Fe were studied (A compo...
متن کاملEffects of Salt Additives to the KOH Electrolyte Used in Ni/MH Batteries
KOH-based electrolytes with different salt additives were investigated to reduce their corrosive nature toward Mg/Ni metal hydride alloys used as negative electrodes in nickel metal hydride (Ni/MH) batteries. Alkaline metal halide salts and oxyacid salts were studied as additives to the traditional KOH electrolyte with concentrations varying from 0.005 M to 1.77 M. Effects of the cations and an...
متن کاملDesign of Hydrogen Storage Alloys/Nanoporous Metals Hybrid Electrodes for Nickel-Metal Hydride Batteries
Nickel metal hydride (Ni-MH) batteries have demonstrated key technology advantages for applications in new-energy vehicles, which play an important role in reducing greenhouse gas emissions and the world's dependence on fossil fuels. However, the poor high-rate dischargeability of the negative electrode materials-hydrogen storage alloys (HSAs) limits applications of Ni-MH batteries in high-powe...
متن کاملClosed-loop Recycling of Nickel, Cobalt and Rare Earth Metals from Spent Nickel-metal Hydride- Batteries
Nickel-metal hydride batteries (Ni-MH) are storers of electrochemical energy, which have a higher specific storage capacity than lead or nickel-cadmium batteries. The demand for Nickel-metal hydride batteries is increasing rapidly since their market launch in the early 1990's. Today there is no suitable and sustainable recycling process to recover nickel, cobalt and rare-earth metals. The disca...
