  1. 1. Fast deep discharging using a controllable load as pretreatment for EV battery recycling : A study on efficacy, speed, and safety

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lucas Van Genechten; [2023]
    Keywords : Recycling; lithium-ion battery; deep discharging; external short-circuit; internal pressure; thermal stability; Electrochemical impedance spectroscopy; Återvinning; litiumjonbatteri; djupurladdning; extern kortslutning; internt tryck; termisk stabilitet; electrochemical impedance spectroscopy;

    Abstract : In response to the present and projected growth of the EV industry, the development of a large-scale, reliable and efficient lithium-ion battery recycling sector is vital to ensure circularity of the embedded valuable metals and ensure overall sustainability of the technology. One of the main recycling procedures under development is based on hydrometallurgy. READ MORE

  3. 2. Numerical Simulations of Metal Recovery for Battery Recycling

    University essay from KTH/Processteknologi

    Abstract : Den pågående elektrifieringen av transport och samhälle kräver utveckling av nya metoder för återvinning av batterier. Hydrometallurgi som fokuserar på selektiv kristallisation av metaller är ett intressant alternativ för dessa ändamål. Dessa system kan studeras genom modellering och simulering. READ MORE

  4. 3. Per- and Polyfluoroalkyl Substance (PFAS) Emissions from Recycling Processes of Lithium-Ion Batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Amanda Rensmo; [2022]
    Keywords : lithium-ion; battery; PFAS; recycling; LIB recycling; ion chromatography; hydrometallurgy; thermal processes; persistent;

    Abstract : The lithium-ion battery (LIB) recycling industry is currently under development to improve the yields for critical metals. However, the organic components of LIBs must also be handled, which may result in harmful chemical emissions as by-products. READ MORE

  5. 4. Separation of Cobalt and Nickel using CYANEX 272 for Solvent Extraction

    University essay from KTH/Kemiteknik

    Author : Caroline Kihlbom; [2021]
