    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid polymer electrolytes; Lithium ion batteries; Ion transport; Polyester; Polycarbonate; Polyketone; Ion coordination; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The field of solid polymer electrolytes (SPEs) used to create safer lithium-ion batteries has been dominated by polyethylene oxide (PEO) since the discovery of its ion-conducting properties in the 1970s. In this thesis, as an alternative, the ion coordination and conduction properties of SPEs based on polyketones, polyesters and polycarbonates are investigated. READ MORE

  6. 24. Using Molecular Dynamics Simulations to Explore Critical Property Relationships in Polymer Electrolytes : Polarity, Coordination, Ionic transport, Ion-pairing, and Ion-ion Correlations

    Author : Harish Gudla; Daniel Brandell; Chao Zhang; Andreas Heuer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid polymer electrolytes; molecular dynamics simulations; solvent polarity; ion-pairing; ion coordination; ion transport mechanisms; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : While ion transport in solid polymer electrolytes (SPEs) has been explored for decades, there still remains controversies about its fundamental properties, often correlated with gaps between experimental and computational studies. Using molecular dynamics simulations to understand the complex transport mechanisms and also to fill these gaps is the main goal of this thesis. READ MORE
