What are nickel/metal hydride rechargeable batteries?

1. Introduction Nickel/metal hydride (Ni/MH) rechargeable batteries are one of the important power sources for various consumer types of mobile applications, stationary energy storage, and, most distinctively, transportation usages.

Who supports the research and development of nickel–metal hydride cells and batteries?

Support for research and development of materials for nickel–metal hydride cells and batteries at VARTA by the Commission of the European Union (CEU) is highly appreciated. The authors thank their numerous colleagues not named individually for their valuable contributions.

Can hydride batteries be recovered from hybrid electric vehicles?

In this study, we analyze the feasibility and life-cycle impacts of recovering critical materials from spent nickel metal hydride batteries from hybrid electric vehicles in the U.S., accounting for stocks, battery scrappage, and end-of-life reverse logistics, given uncertain future availability scenarios.

Do recovered materials reduce environmental impacts in NiMH battery manufacturing?

The authors find that environmental impacts decrease when recovered materials (specifically, iron, mixed RE metals, and nickel) replace their associated virgin materials in NiMH battery manufacturing.

How does transportation impact the environmental impact of a NiMH battery?

Transportation environmental impacts from moving spent NiMH batteries from collection centers to storage and ultimately to the recycling facilities are calculated assuming a 16–32 tonne diesel-powered long-haul freight truck, and using the average distance traveled by 1000 kg of spent battery scrap over the analysis time horizon.

Do life-cycle assessments elucidate the environmental impact of NiMH battery recycling?

Whereas life-cycle assessments (LCAs) can elucidate the environmental impacts of NiMH battery production, use, and recycling, only a few studies have assessed the environmental impact of NiMH battery recycling.
