  1. 6. Highly Concentrated Electrolytes for Lithium Batteries : From fundamentals to cell tests

    Författare :Viktor Nilsson; Kristina Edström; Patrik Johansson; Erik Berg; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; SEI; Highly concentrated electrolyte; Al corrosion; Li metal battery;

    Sammanfattning : The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. LÄS MER

  3. 7. From Current Collectors to Electrodes : Aluminium Rod Structures for Three-dimensional Li-ion Micro-battery Applications

    Författare :Gabriel Oltean; Kristina Edström; Leif Nyholm; Erik Kelder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D micro-batteries; aluminium; titanium oxide; current collectros; negative electrodes; electrodepostion; electrophoretic depostion; sol-gel synthesis;

    Sammanfattning : The potential use of 3D aluminium nanorod structures as current collectors and negative electrodes for 3D Li-ion micro-batteries was studied based on the use of relatively simple and cost-effective electrochemical and sol-gel deposition techniques.Aluminium rod structures were synthesised by galvanostatic electrodeposition using commercial porous membranes as templates.

  4. 8. Professional Support Staff at Higher Education Institutions : Navigating Ambiguities in Hybrid Roles

    Författare :Malin Ryttberg; Lars Geschwind; Anders Broström; Linda Wedlin; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teknikvetenskapens lärande och kommunikation; Education and Communication in the Technological Sciences;

    Sammanfattning : This thesis focuses on how professional support staff within the support services at higher education institutions (HEIs) perceive their roles. A combination of the broader expectations on HEIs from the surrounding society, changed ideals for governance and research indicating changed profiles for the roles of these support staff has motivated this research.
