Twist-Shaped CuO Nanowires as Anode Materials for Lithium Ion Batteries

الملخص EN

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−1 and maintained a reversible capacity of 320 mAh g−1 over 50 cycles at the current density of 100 mA g−1.

Thus, 1D twist-shaped CuO nanowires provide a new insight into the development of anode materials for next-generation high performance lithium ion batteries.
