Preparation and electrochemical properties of SnO2 nanowires for application in lithium-ion batteries

Journal Article


Abstract


  • One-dimensional (1D) nanostructured materials have

    received considerable attention for advanced functional

    systems as well as extensive applications owing to their

    attractive electronic, optical, and thermal properties.[1–2] In

    lithium-ion-battery science, recent research has focused on

    nanoscale electrode materials to improve electrochemical

    performance. The high surface-to-volume ratio and excellent

    surface activities of 1D nanostructured materials have

    stimulated great interest in their development for the next

    generation of power sources.[3–4]

    Materials based on tin oxide have been proposed as

    alternative anode materials with high-energy densities and

    stable capacity retention in lithium-ion batteries.[5–7] Various

    SnO2-based materials have displayed extraordinary electrochemical

    behavior such that the initial irreversible capacity

    induced by Li2O formation and the abrupt capacity fading

    caused by volume variation could be effectively reduced when

    in nanoscale form.[8–10] From this point of view, SnO2 nanowires

    can also be suggested as a promising anode material

    because the nanowire structure is of special interest with

    predictions of unique electronic and structural properties.

    Furthermore, the nanowires can be easily synthesized by a

    thermal evaporation method. However, in its current form,

    this method of manufacture of SnO2 nanowires has several

    limitations: it is inappropriate for mass production as high

    synthesis temperatures are required and there are difficulties

    in the elimination of metal catalysts that could act as

    impurities or defects. This results in reversible capacity loss

    or poor cyclic performance during electrochemical reactions.[

    11, 12] The critical issues relating to SnO2 nanowires as

    anode materials for lithium-ion batteries are how to avoid the

    deteriorative effects of catalysts and how to increase production.
