High‐performance asymmetric super‐capacitors containing thick‐film electrodes (over 100 μm thick) made of CNT/V 2 O 5 nanowire composite are designed. The excellent conductivity, high specific capacitance, and a large voltage window of the CNT/V 2 O 5 nanocomposite enable the fabrication of devices with high energy and high power densities. Moreover, the resulting devices exhibit excellent cycling stability. This supercapacitor approach may be attractive for a wide range of device applications.
