奈米結構結合過渡金屬氧化物或氫氧化物所製成的奈米複合電極，擁有高功率密度、良好的能量密度及多次掃描電容值穩定性，被認為是一種非常好的超級電容型態。本研究利用氧化鋅奈米線做為活性材料的支架，在上面沉積鎳鈷氫氧化物，製作成奈米複合電極。首先利用化學浴沉積法將氧化鋅奈米線生長在碳纖維布上，接著利用脈衝電化學沉積法將鎳鈷氫氧化物沉積在氧化鋅奈米線表面，並對電化學的沉積參數及鎳鈷鍍液比例做系統的探討。最後由最佳參數所沉積出的鎳鈷氫氧化物/氧化鋅奈米線/碳纖複合電極，在10 mV/s的掃描速率下有880.5 F/g的比電容值。

Transition-metal oxides or hydroxides on nanostructured supports have been regarded as promising electrode materials for high-performance supercapacitors due to their high power density, good energy density, excellent cycle stability, and long lifetime. In this work, a high-performance supercapacitor based on NixCo1-x(OH)2 nanoflakes modified ZnO nanowires (NWs) was developed. The ZnO NWs were synthesized on carbon fiber (CF) by chemical bath deposition, followed by pulse electrodeposition of NixCo1-x(OH)2 nanoflakes on the surface of ZnO NWs. The effects of the electrodeposition conditions along with the precursor variables were systematically investigated. The NixCo1-x(OH)2/ZnO NWs/CF hybrid nanostructure fabricated under the optimal conditions has exhibited a specific capacitance of 880.5 F/g, good rate capability, and cycling stability.
