  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. Phenomenological Swelling Model of Battery Module

    University essay from KTH/Hållfasthetslära

    Author : Abhiram Lakshmipuram Govindaraj; [2022]
    Keywords : State-of-Charge; Swelling Force; Compression Pads; Laddningsgrad; svällningskraft; kompressionsdynor;

    Abstract : Lithium-ion batteries (LiBs) are the most popular choice in the shift towardselectrification due to their high volumetric energy and power density. An importantaspect to study is the effect of swelling on the mechanical performance of LiBsas it plays an important role in determining the forces in the battery module. READ MORE

  4. 3. Design of tunnel support for single zones with swelling clay

    University essay from KTH/Jord- och bergmekanik

    Author : Taha Faris Nihayat; [2022]
    Keywords : Swelling clay; Rock support; Weakness zone; Design; Tunnel;

    Abstract : Swelling clay is an important and challenging geological feature in tunnelling projects.The behaviour of swelling clay is influenced by many internal and external factors.This, combined with a lack of experience and knowledge has resulted in challengeswhen accounting for the swelling phenomena.

  5. 4. Testbed Development for Non-invasive Intracranial Pressure Monitoring with a Microwave based Electromagnetic Skin Patch Sensor

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Sandra Palm; Hassan Saado; [2021]
    Keywords : Intracranial pressure; Artificial cerebrospinal fluid; Biomedical engineering; Microwave sensor;

    Abstract : Traumatic brain injuries (TBIs) are a major public health problem worldwide where the symptoms can be anything from mild concussion to severe swelling of the brain tissue. As a result of TBI the intracranial pressure (ICP) can elevate to pathological levels with severe consequences such as hypoxia, ischemia and brain hemorrhage. READ MORE

  6. 5. Surface functionalization of nonwoven polypropylene with BTCA polycarboxylic acid in supercritical carbon dioxide medium

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Md Fahad Khan; [2021]
    Keywords : Nonwoven polypropylene; Supercritical carbon dioxide; Surface functionalization; 1; 2; 3; 4- Butanetetracarboxylic acid; Impregnation; Environmentfriendly; Hydrophilicity;

    Abstract : Nonwoven polypropylene has been utilized broadly in various hygienic and medical textile applications because of its excellent mechanical properties, chemical resistance, and minimal expense contrast with other synthetic polymers. However, the insufficiency of surface tethering groups, including adhesion, wettability, and hydrophilicity, some applications are not convenient on nonwoven polypropylene surfaces such as dyeing, printing, attachment of antibacterial and bioactive agents.
