2016 Journal of Nanomaterials  
Twist-shaped CuO nanowires were synthesized by two-step method consisting of solution reaction and then heat treatment. The as-synthesized samples were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). When evaluated as anode materials for lithium ion batteries, twist-shaped CuO nanowires showed a high initial discharge capacity of 983 mAh g−1and maintained a reversible capacity of 320 mAh g−1over 50 cycles at the current density of 100 mA g−1. Thus, 1D
