The rapidly growing battery industry and the corresponding potential environmental
pollution make recycling waste nickel (Ni)-based batteries essential. This review …

This work proposes a review of the various unit operations described in the literature for the
specific recycling of nickel metal hydride batteries, with a large focus on the chemical …

Due to their large variety of applications, their low supply and high demand, the rare earth
elements (REEs) are presently viewed as being among the most critical chemical elements …

Nickel is an important metal, heavily utilized in industry mainly due to its anticorrosion
properties. As a consequence, nickel containing wastes such as spent batteries and …

Production of LiBs and NiMH batteries is expected to increase rapidly due to the soaring
price of oil and gas which increases interest in renewable energy as well as the introduction …

The purpose of this work is to describe and review the current status of the recycling
technologies of spent NiMH batteries. In the first part of the work, the structure and …

The separation of rare earth elements, cobalt and nickel from NiMH battery residues is
evaluated in this paper. Analysis of the internal content of the NiMH batteries shows that …

The separation of nickel (II), cobalt (II) and lanthanides from chloride leach liquors of spent
nickel-metal hydride (Ni-MH) batteries is described. After leaching in 12molL− 1 HCl, the …

A hydrometallurgical procedure has been developed for the separation and recovery of
nickel, cobalt and rare earths (RE) from spent Ni–MH batteries. In the process of separation …

In a circular economy context, there is a growing need for more sustainable waste
management options to recover elements from end-of-life materials. These “secondary ores” …
