  1. 6. Structural Lithium Ion Battery Electrolytes

    Författare :Niklas Ihrner; Mats Johansson; Daniel Brandell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structural batteries; Structural battery electrolyte; Lithium ion batteries; Polymerization induced phase separation; Carbon fibers; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : A major challenge in the electrification of vehicles in the transport industry is that batteries are heavy, which reduces their effectiveness in mobile applications. A solution to this is structural batteries, which are batteries that can carry mechanical load while simultaneously storing energy. LÄS MER

  3. 7. 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
