Electrodeposition of Ni5Sb2 nanowires array and its application as a high-performance anode material for lithium ion batteries
Single crystal Ni5Sb2 nanowires array is synthesized by direct-current electrodeposition technique. The initial specific discharge and charge capacity of the as-produced Ni5Sb2 nanowires array electrode as an anode material for lithiumion batteries presents 290.6mAhg?1 and 225mAhg?1 respectively at a current density of 60mAg?1. Its chargedischarge curve displays an excellent platform. Initial coulombic efficiency of the electrode is above 77%, and it becomes greater than 95% after several charge/discharge cycles.
