    Nyckelord :Lithium-ion battery; thermal runaway; accelerating rate calorimetry; electrochemical impedance spectroscopy; thermal management; Litiumjonbatteri; termisk rusning; kalorimeter; elektrokemisk impedansspektroskopi; värmereglering;

    Sammanfattning : The Swedish Armed Forces are investigating high-risk applications where lithium-ion batteries (LIB) can replace traditional lead-acid batteries. Understanding the potential safety risks and evaluating a battery's instability is crucial for military applications. LÄS MER

  5. 4. Relationship Between Hekla’s Magmatic System and Its Eruptive Behavior

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Eric Andin; [2017]
    Nyckelord :Hekla; crystal mush; thermobarometry; magma storage depth; Hekla; kristallansamling; termobarometri; magmalagringsdjup;

    Sammanfattning : The southern part of Iceland incorporates two parallel volcanic zones, the Eastern Volcanic Zone and the Western Volcanic Zone. These two branches are connected by an E-W transform. Hekla is located close to intersection between the two plate boundaries. Hekla is one of Iceland's most active and explosive volcanoes. LÄS MER

  7. 5. Volatilernas påverkan på marina vulkanutbrott

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper
