  1. 6. Sustainable Recycling of Spent Lithium-ion Batteries : An In-situ Approach for Recovery and Alloying of Valuable Metals

    Författare :Safoura Babanejad; Hesham Ahmed; Charlotte Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; black mass; Recycling; Pyrometallurgy; modeling; Process Metallurgy; Processmetallurgi;

    Sammanfattning : A large number of Li-ion batteries used today will reach their End-Of-Life (EOL) in a few years. After their EOL, the recovery of their precious elements is required. By applying physical separation, a fraction with fine particle size is left behind which is known as Black Mass (BM). LÄS MER

  4. 8. Lignin- and PAN-based carbon fibres as negative electrodes for alkali-ion batteries

    Författare :Kevin Peuvot; Göran Lindbergh; Dan Zenkert; Enn Lust; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hard carbon; lithium-ion batteries; sodium-ion batteries; potassium-ion batteries; lignin-based carbon fibres; PAN-based carbon fibres; free-standing electrodes; Chemical Engineering; Kemiteknik;

    Sammanfattning : The development of sodium-ion batteries (SIBs) and potassium-ion batteries (KIBs) have accelerated since they can now reach similar gravimetric energy densities as lithium-ion batteries (LIBs) but with a lower environmental impact. Hard carbon is the most common negative electrode for SIBs and KIBs and can be made from renewable resources such as lignin. LÄS MER

    Sammanfattning : Surface film formation at the electrode/electrolyte interface in lithium-ion batteries has a crucial impact on battery performance and safety. This thesis describes the characterisation and treatment of electrode interfaces in lithium-ion batteries. LÄS MER

  7. 10. Investigation of HEV Li-ion Batteries for Lithium Recovery

    Författare :Sravya Kosaraju; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LiFePO4 electrode; Li-ion battery recycling; Li recovery; Solvent Extraction; Dissolution study; Characterization;

    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
