摘　　要：本研究采用电化学沉积的方法在金属钛板上制备出镍尖锥的规则阵列,然后将二氧化锰直接沉积到镍尖锥阵列上。这种沉积有二氧化锰的镍尖锥能够直接从基板上剥落下来形成自支撑的、柔性、超薄电极片。结果显示该电极的最高比电容达到325 F/g,并且具有出色的倍率性能。用这种电极组装成的柔性超薄超级电容器呈现出良好的电化学性能,有望在可穿戴消费电子领域得到应用。MnO2 was deposited on Ni nanocone arrays through electrochemical deposition process, to enhance the electrochemical performance. The as-prepared MnO2/Ni nanocone electrode can be peeled off from the substrate and used as freestanding, lfexible, and ultrathin supercapacitor electrode. Its speciifc capacitance is as high as 325 F/g. The electrode also shows excellent rate performance. The lfexible and ultrathin asymmetric supercapacitor based on the MnO2/Ni nanocone elelctrode demostrates good electrochemical performance. The device possesses promising applications in the ifeld of energy storage.
