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

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

    Abstract : 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. READ MORE

  4. 2. Sodium Batteries: From Liquid to Polymer Electrolytes

    Author : Andrea Boschin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electrochemical solid state cells; polymer electrolytes; sodium batteries; liquid electrolytes;

    Abstract : 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. READ MORE

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

    Author : Markus Willgert; Mats Johansson; Alexander Bismarck; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  6. 4. Molecular Interactions and Dynamics in Lithium Conducting Electrolytes

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

    Abstract : 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.

  7. 5. Ordering in Crystalline Short-Chain Polymer Electrolytes

    Author : Anti Liivat; Joseph Nordgren; Josh Thomas; Daniel Brandell; David Brown; Uppsala universitet; []
    Keywords : Atomic and molecular physics; polymer electrolytes; molecular dynamics; ionic conductivity; crystalline ordering; polymer chain length; smectic; nematic; Atom- och molekylfysik;

    Abstract : Polymer electrolytes are the most obvious candidates for safe "all-solid" Li-ion batteries and other electrochemical devices. However, they still have relatively poor ionic conductivities, which limits their wider adoption in commercial applications. READ MORE
