摘要：
SnO2 nanorod arrays have been prepared on large-area flexible metallic substrates (Fe-Co-Ni alloy and Ni foil) via a hydrothermal process for the first time and have been demonstrated as a high-performance anode material for lithium ion batteries. Electrochemical behavior is found to depend crucially on the structural parameters of the array. An array consisting of SnO 2 nanorods of average 60 nm in diameter and 670 nm in length delivers a reversible capacity of as high as 580 mAh g-1 after 100 cycles (at 0.1C) and shows excellent rate capability (350 mAh g-1 at the 5C rate). Structural disint...
