  • Nickel-metal hydride (NiMH) battery recycling
    Patent number: 12597652
    Abstract: Recycling of nickel-metal hydride (NiMH) batteries extracts substantially pure nickel based on adding a leach agent to granular cathode material resulting from agitation of the NiMH batteries to form a leach solution. A pH of the leach solution is maintained for precipitating iron, aluminum and lanthanide rare earth elements (REE) for yielding a nickel solution for forming a cathode material precursor in a recycled battery, often with a high nickel content.
