Nickel Metal Hydride Battery Waste: Mechano-hydrometallurgical Experimental Study on Recycling Aspects

Closed-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...

Nickel-Metal Hydride Batteries For ZEV-Range Hybrid Electric Vehicles

Hybrid electric vehicles with significant all-electric range provide a promising alternative to zero emission vehicles (ZEVs) without the problem of the limited range of electric vehicles. Ovonic nickel-metal hydride (NiMH) batteries feature a combination of high power and energy density ideal for ZEV-range hybrid electric vehicles. A series of high-power, highenergy batteries ranging in size f...

Recycling and Solid Waste Study:

In this paper we aim to determine how the city of Eugene, Oregon compares to other cities in terms of its citizens’ willingness-to-pay (WTP) for recycling service. Also, we will determine what the expected WTP for Eugene residents and use that result to make policy recommendations. We use WTP as an indication of a city’s relative valuation of recycling services in their community. We will use W...

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...
