    Abstract : The potentially most important challenges today are related to energy and the environment. New materials and methods are needed in order to, in a sustainable way, convert and store energy, reduce pollution, and clean the air and water from contaminations. READ MORE

  2. 2. Comparison of incineration and pyrolysis of NMC-lithium-ion batteries – determination of the effects on the chemical composition, and potential formation of hazardous by-products

    Author : Gabriele Lombardo; Chalmers University of Technology; []
    Keywords : vacuum; recycling; carbothermal; Keywords: Lithium-ion batteries; incineration; pyrolysis.;

    Abstract : Several industrial lithium battery recycling processes use thermal pre-treatment in an oxidative or inert atmosphere, or in a vacuum, to separate the battery components and remove organic material. However, a comparison of these pre-treatments on the microstructure and composition of waste material and production scrap LiBs has not been explored as well as there is a scarcity of information about the character of by-products generated during the processing.

  3. 3. Effects of pyrolysis and incineration on the chemical composition of Li-ion batteries and analysis of the by-products

    Author : Gabriele Lombardo; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; NMC batteries; carbothermic reduction; pyrolysis; Lithium-ion batteries; metal recycling;

    Abstract : In the present work, the effects of pyrolysis and incineration on the composition of Li-ion battery cell materials and their dependence on treatment time and temperature were investigated. Waste from Li-ion batteries was treated at 400˚, 500˚, 600˚, and 700˚C for 30, 60, and 90 minutes. READ MORE
