  4. 7. Fluorine-Free Phosphorus-Based Ionic Materials and Electrolytes

    Author : Yanqi Xu; Faiz Ullah Shah; Patrik Johansson; Jonas Örtegren; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorine-free electrolytes; Physiochemical properties; Nuclear magnetic resonance; Ion interactions; Single crystal structures; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Due to the successful commercialization of lithium-ion batteries (LIBs), there is a growing interest in developing new battery materials with beneficial electrochemical properties. However, the uneven distribution of lithium resources and the low abundance of lithium in the earth crust are the main obstacles for further development and large-scale production of LIBs. READ MORE

  5. 8. Coated Surfaces for Inkjet-Printed Conductors

    Author : Thomas Öhlund; Hans-Erik Nilsson; Jonas Örtegren; Jouko Peltonen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet; Nanoparticles; Paper; Flexible substrates; Sintering; Printed Electronics; Functional Printing;

    Abstract : In this thesis, a number of commercially available paper substrates of various types are characterized and their characteristics related to the performance of inkjet-printed conductors using silver nanoparticle ink. The evaluated performance variables are electrical conductivity as well as the minimum achievable conductor width and the edge raggedness. READ MORE
