The effect of morphological modification on the electrochemical properties of SnO₂ nanomaterials

The electrochemical performances of 1D SnO₂ nanomaterials. nanotubes, nanowires, and nanopowders, are compared to define the most favorable morphology when SnO₂ nanomaterials are adopted as the electrode material for lithium-ion batteries. Changes in the morphology of SnO₂ are closely related with its electrochemical performance. Some SnO₂ nanomaterials feature not only an increased energy density but also enhanced Li⁺ transfer. The correlation between the morphological characteristics and the electrochemical properties of SnO₂ nanomaterials is discussed. The interesting electrochemical results obtained here on SnO₂ nanomaterials indicate the possibility of designing and fabricating attractive nanostructured materials for lithium-ion batteries.
