Recycling of nickel metal hydride (NiMH) batteries; Characterization and recovery of nickel, AB5 alloy and cobalt

  title={Recycling of nickel metal hydride (NiMH) batteries; Characterization and recovery of nickel, AB5 alloy and cobalt},
  author={Filip Holmberg},
Nickel metal hydride (NiMH) batteries are used today for applications that can assist in the adaptation toward carbon-neutral energy sources (i.e. hybrid vehicles and smart grids). Recovery of metals such as nickel, cobalt and rare earth elements (REEs) from discarded NiMH batteries is important for economic and/or technological reasons. Recirculation of valuable materials back into society can be achieved by the production of pure concentrates of elements from waste, or by regenerating and… 

Recycling of spent lithium nickel-cobalt batteries through leaching of nickel and cobalt from cathode material

This research paper investigates a hydrometallurgical approach that includes the leaching of spent lithium-ion battery cathode material. The targeted elements to be recovered are cobalt and nickel

Leaching mechanisms of industrial powders of spent NiMH batteries in a pilot-scale reactor.

A selective dissolution of REEs with respect to nickel for both acid at pH 3, attributed to (i) the kinetic inhibition of nickel metal dissolution and (ii) the specific core-shell structure of aged mischmetal particles.

Leaching mechanisms of industrial powders of spent nickel metal hydride batteries in a pilot-scale reactor

ln view of a sustainable recycling process, the leaching mecha­ nisms of nickel and rare-earth elements (REEs) contained within industrial samples of spent nickel metal hydride battery powders were

Impact of battery cell imbalance on the voltage behavior of commercial Ni-MH EV/HEV battery modules

Electric and hybrid-electric vehicles’ (EV/HEV) battery packs typically are composed of hundreds of single battery cells, which are usually grouped in modules and installed in a pack to collectively

Characterization of the gas composition inside NiMH batteries during charge using GC-MS

The aim of the project was to develop a method to measure and studythe degree of activation of the negative electrode (MH) in a NiMH battery.This was done by characterization of the gases produced ...



Characterization of spent nickel–metal hydride batteries and a preliminary economic evaluation of the recovery processes

Results of this study show that metallic components account for more than 60% of battery weight, when Ni, Fe, Co, and rare earth elements (REEs) were 17.9%, 15.4%, 4.41%, and 17.3%, respectively, in a single battery.

Recycling of nickel–metal hydride batteries. I: Dissolution and solvent extraction of metals

Nickel–metal hydride batteries contain valuable metallic components and although they are not considered a hazardous waste, recovery of these materials is necessary from an economic point of view. In
