Abstract

Finding a reliable synthetic route of anode materials for lithium ion batteries (LIBs) is a pivotal area of research. Here, a facile method is developed to synthesize porous nanowires and thorn like copper oxide (CuO) using a non-ionic surfactant, Tween-80 for LIBs. Tween-80 serves as an effective template in directing the growth of nanowires and thorn-like CuO, in both low and high temperatures hydrothermal synthesis procedures. The products are characterized by XRD, FTIR, TGA, SEM, TEM, XPS and BET. When evaluated as anode material for LIBs, CuO nanowires exhibited better capacity retention with a record high reversible capacity of over 506.6 mAh g−1 for up to 50 cycles as compared to thorn-like CuO which delivers reversible capacity of only 430.4 mAh g−1. The better electrochemical performance is attributed to the porous nature of the products and this simple synthetic route makes CuO nanowires a potential future anode material for LIBs.
