The recycling of nickel-metal hydride batteries (NiMHBs) has garnered significant attention in recent years due to the growing demand for critical metals and the implementation of national and international legislation. ••Existing strategies and technologies in group recovery of REEs from. DBP Dibenzyl phosphateDMG DimethylglyoximePEG. Rare earth elements (REEs) are a group of metals comprising 15 lanthanides, as well as yttrium and scandium. These elements are naturally present in various minerals, includin. Due to the hydrogen-absorbing properties of nickel-lanthanide alloys, REEs have been utilized in energy storage since the early '90s, leading to their extensive use in nickel-metal hydri. The preliminary processing of NiMHBs usually includes discharging (to avoid short circuits), opening of casings, liberation of seals and separators, shredding, and separation of diff.

Why are rare earth elements important?
5. Conclusions Rare earth elements (REEs) are of strategic importance for the world's technological development and play a crucial role in the ongoing efforts towards a more sustainable and environmentally friendly future.
Graphical abstract Various techniques have been proposed for the recovery of REEs from Ni-MH batteries, including hydrometallurgical and pyrometallurgical methods. Hydrometallurgical methods involve the extraction and purification of REEs from aqueous media, while in pyrometallurgical methods, REEs are recovered at high temperatures.
