    Sammanfattning : Automobile electrification is one of the technological developments that may establish aneco-friendly transport system by mitigating vehicle emissions, and hopefully lead to a lessfossil fuel-dependent society. Conservative forecasts predict four million electric cars onthe road by 2015 (Bernhart et al., 2012). LÄS MER

  3. 7. Hydrometallurgical Treatment of Neodymium Magnet Waste

    Författare :Marino Gergoric; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; recycling; rare-earth elements; leaching; Keywords: neodymium magnets; solvent extraction;

    Sammanfattning : Recent decades have seen a considerable increase in the usage of rare-earth elements (REEs) in modern technologies and green energy sources. Recycling of REEs out of end-of-life products and E-scrap has become an alternative to mining them out of primary ores due to their supply risk in some countries and the development towards circular economies.

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

    Författare :Filip Holmberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recycling; nickel; AB5 alloy; cobalt; NiMH battery; hydrogen storage alloy; leaching;

    Sammanfattning : 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. LÄS MER
