In this work, we have employed a facile and cost-effective synthetic method to fabricate zinc oxide nano-flakes decorated carbon nanofibers as a promising electrode material for supercapacitors. The morphology of the as-prepared ZnO/CNFs composites clearly showed that the zinc oxide nano-flakes decorated the surface of carbon nanofibers. The electrochemical performacnes of the as-prepared prepared ZnO/CNFs composites was evaluated via cyclic voltammetry, galvanostatic charge-discharge, and EIS technique in the three-electrode system. The ZnO/CNFs composites possessed superior specific capacitance of 260 F/g at 5 mV/s and good capacity retention of 73.3 % after 1000 CV cycles. This synthesis method provides a new synthetic protocol for utilizing ZnO-based materials as the electrode materials for supercapacitors.
