The electrochemical performances of 1D SnO 2 nanomaterials, nanotubes, nanowires, and nanopowders, are compared to define the most favorable morphology when SnO 2 nanomaterials are adopted as the electrode material for lithium‐ion batteries. Changes in the morphology of SnO 2 are closely related with its electrochemical performance. Some SnO 2 nanomaterials feature not only an increased energy density but also enhanced Li + transfer. The correlation between the morphological characteristics and the electrochemical properties of SnO 2 nanomaterials is discussed. The interesting electrochemical results obtained here on SnO 2 nanomaterials indicate the possibility of designing and fabricating attractive nanostructured materials for lithium‐ion batteries.
