Abstract
We investigate the anode performance of Si-based nanorods by tuning its composition using an oblique (co)deposition technique. Our results show that pure Si nanorods have a higher initial anodic capacity of 1500 mAh g -1, but the capacity diminishes after 50 cycles due to the morphological change and pulverization. By introducing approximately 70 at.% Cu into Si nanorods, the Si-Cu composite nanorods demonstrate 500 mAh g -1 of capacity sustainable in 100 cycles, which is attributed to the flexibility and improved toughness of Si-Cu composite nanorods. © 2011 Elsevier B.V.
