  • Improving the volumetric capacity of TiO₂ nanomaterials used as anodes in lithium-ion batteries 

    Wang, Yuan (University of St Andrews, 2015-06-24) - Thesis
    The experimental data presented in this thesis demonstrates the preparation and characterization of TiO₂ polymorphs (anatase and TiO₂-(B)) in the form of nanomaterials. The reduced dimension of the nanomaterials amplifies ...
  • ‘Isofacet’ anatase TiO2 microcages : topotactic synthesis and ultrastable Li-ion storage 

    Wu, Qili; Yang, Xianfeng; Zhou, Wuzong; Gao, Qiong; Lu, Fengqi; Zhuang, Jianle; Xu, Xianfang; Wu, Mingmei; Fan, Hong Jin (2015) - Journal article
    A new type of anatase TiO2 microcages assembled by oriented nanocrystals have been successfully fabricated through a topotactical conversion from CaTiO3 microcage precursor. The anatase microcages have all their six side ...
  • Novel lithium-ion host materials for electrode applications 

    Lyness, Christopher (University of St Andrews, 2011-06-22) - Thesis
    Two novel lithium host materials were investigated using structural and electrochemical analysis; the cathode material Li₂CoSiO₄ and the LiMO₂ class of anodes (where M is a transition metal ion). Li₂CoSiO₄ materials were ...
  • Novel routes to high performance lithium-ion batteries 

    Drewett, Nicholas E. (University of St Andrews, 2013-06-26) - Thesis
    This thesis investigates several approaches to the development of high-performance batteries. A general background to the field and an introduction to the experimental methods used are given in Chapters 1 and 2 ...
  • Polymer electrolytes : synthesis and characterisation 

    Maranski, Krzysztof Jerzy (University of St Andrews, 2013-06-26) - Thesis
    Crystalline polymer/salt complexes can conduct, in contrast to the view held for 30 years. The alpha-phase of the crystalline poly(ethylene oxide)₆:LiPF₆ is composed of tunnels formed from pairs of (CH₂-CH₂-O)ₓ chains, ...
  • Titanium dioxide nanomaterials as negative electrodes for rechargeable lithium-ion batteries 

    Gentili, Valentina (University of St Andrews, 2011-11-30) - Thesis
    Titanium dioxide, TiO₂, materials have received much attention in recent years due to their potential use as intercalation negative electrodes for rechargeable lithium-ion batteries. The aim of this doctoral work was to ...
