Linear attachment of Li1 + αV3O8nanosheets to 1-dimensional (1D) arrays: fabrication, characterization, and electrochemical properties

Abstract

1D arrays of Li_{1 + α}V₃O₈ nanosheets have been fabricated by using electrospinning combined with the sol–gel process. The 1D nanostructures, depending on the anisotropic nature of the sol precursor, can be changed by adjusting the calcining temperature and electrospinning parameters. In the present work, the microstructure and formation mechanism of 1D nanostructures are studied, and their initial discharge capacity as the positive electrode material for lithium ion batteries is ca. 352 mAh g⁻¹ and remains ca. 255 mAh g⁻¹ after 40 cycles, which gives higher charge–discharge capacities and better cycle performance compared to the separated Li_{1 + α}V₃O₈ nanosheets.
