  1. 1. Fundamental Insights into the Electrochemistry of Tin Oxide in Lithium-Ion Batteries

    Författare :Solveig Böhme; Leif Nyholm; Kristina Edström; Laure Monconduit; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tin; Tin oxide; Lithium-ion batteries; Electrochemistry; High temperature cycling; Conversion reaction; XPS; SEM; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : This thesis aims to provide insight into the fundamental electrochemical processes taking place when cycling SnO2 in lithium-ion batteries (LIBs). Special attention was paid to the partial reversibility of the tin oxide conversion reaction and how to enhance its reversibility. LÄS MER

    Sammanfattning : Many materials exhibit interesting and novel properties when prepared as thin films. Thin film metal oxides have had an impact on the technological progress of the microelectronics mainly due to their electrical and optical properties. LÄS MER

  5. 4. Lithium intercalation in tin oxide films : Physics and electrochemistry

    Författare :Jan Isidorsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Tin oxide films were made by reactive rf magnetron sputtering under conditions that led to both electronic and ionic conductivity. It was found that a high sputter pressure promoted porosity and a high charge capacity. LÄS MER

  7. 5. Transparent Conductive Tin Doped Indium Oxide : Characterisation of Thin Films Made by Sputter Deposition with Silver Additive and by Spin Coating from Nanoparticle Dispersions

    Författare :Annette Hultåker; Peter van Nijnatten; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Thin films of tin doped indium oxide (ITO) were prepared by two different methods: by sputter deposition with silver additive and by spin coating of a nanoparticle dispersion.ITO films doped with ≤ 20 at% of silver were prepared either as homogenous blends of ITO and silver or as intermixed layers.
