    Sammanfattning : The electrolyte is a key component in high-capacity lithium batteries and there is a large demand for improved materials to increase the performance. Polymer-based electrolytes offer advantages in the design of safer and lighter batteries. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Markus Willgert; KTH.; [2014]
    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
