With the advent of flexible electronics, flexible secondary rechargeable batteries have attracted considerable attentions as a promising power source in the new generation of flexible electronics such as roll-up displays, smart electronics, and implantable medical devices. In this work, we report the fabrication of 3D NiCo2O4 arrays on carbon cloth as a binder-free anode for sodium/lithium ion storage. Amorphous carbon layer is used to modify the surface of NiCo2O4 arrays by physical vapor deposition (PVD). The electrochemical performance measurements demonstrate that the amorphous carbon layer can improve the electrochemical stability of NiCo2O4. The NiCo2O4@ C/carbon cloth electrode exhibits a high reversible capacity of 749.9 mAh gâ1, stable cycling with more than 535.47 mAh gâ1 at 500 mA gâ1 over 100 cycles and impressive rate capability (318 mAh gâ1 at 5 A gâ1 over 700 cycles) for SIBs and excellent electrochemical performance for LIBs (reversible capacity of 807.63 mAh gâ1 were observed for 100 cycles).
