    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electrochemical solid state cells; polymer electrolytes; sodium batteries; liquid electrolytes;

    Sammanfattning : Today lithium-ion batteries (LIBs) are dominating the field of rechargeable batteries for portable devices. More recently LIBs have also been considered for large-scale applications, such as in the areas of electromobility and grid storage. LÄS MER

  4. 3. Innovative Polymer Hosts for Solid Lithium-ion Battery Electrolytes

    Författare :Orpita Majumdar Svensson; Tim Melander Bowden; Daniel Brandell; Georgina Gregory; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : Current electrolytes used in lithium ion batteries are flammable and volatile organic liquids that are fundamentally unstable at the operational voltage of the cells, posing a significant safety risk. A practical approach to get over this obstacle is to substitute the liquid electrolyte solution with a solid (solvent-free) polymer electrolyte (SPE), which is a solution of a lithium salt in a solid polymer matrix.

  5. 4. Solid Polymer Lithium-Ion Conducting Electrolytes for Structural Batteries

    Författare :Markus Willgert; Mats Johansson; Alexander Bismarck; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This work comprises the manufacture and characterization of solid polymer lithium ion conducting electrolytes for structural batteries. In the study, polymer films are produced in situ via a rapid versatile UV irradiation polymerization route, in which ethylene oxide methacrylates are polymerized into thermoset networks. LÄS MER

  7. 5. Molecular Interactions and Dynamics in Lithium Conducting Electrolytes

    Författare :Josefina Adebahr; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ab initio calculations; plastic crystals; nanocomposite polymer electrolytes; NMR; Raman spectroscopy; gel electrolytes; polymer electrolytes;

    Sammanfattning : Lithium conducting electrolytes, suitable for battery applications, have been characterized on a molecular level using Raman spectroscopy, ab initio calculations and nuclear magnetic resonance spectroscopy, in order to better understand molecular and ionic interactions and dynamics in the systems. Three different types of electrolytes have been investigated; polymer gel electrolytes, solid polymer electrolytes and plastic crystal materials, with the main focus on the polymer based electrolytes.
