  1. 1. Block Copolymer Electrolytes : Polymers for Solid-State Lithium Batteries

    Författare :Andreas Bergfelt; Tim Bowden; Daniel Brandell; Yoichi Tominaga; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The use of solid polymer electrolytes (SPEs) for lithium battery devices is a rapidly growing research area. The liquid electrolytes that are used today are inflammable and harmful towards the battery components. LÄS MER

  2. 2. 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.

    Sammanfattning : Based on the atomic postulate, which is now more than 2400 years old, scientists have developed very advanced tools for studying the material world. With the potential realized with modern computers, more and more sophisticated methods are available for predicting real material properties, even from simple theoretical model systems. LÄS MER

  5. 5. Studies on some pyrochlore type solid electrolytes

    Författare :Jekabs Grins; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This article summarizes ionic conductivity studies on a number of compounds crystallizing in the pyrochlore type structure. The pyrochlore structure is described, and the determination of ionic conductivities by means of impedance measurements is discussed. LÄS MER
