AB  - Hybrid supercapacitors (HSCs) with the characteristics of high energy density, 
      long cycle life and without altering their power density need to be developed 
      urgently. Herein, a novel dual-ion hybrid supercapacitors (DHSCs) with Ni(OH)(2) 
      nanotube arrays (NTAs) as positive electrode and V(2)O(5) directly grown on 
      freestanding carbon nanotubes (CNTs) as negative electrode is assembled. In 
      charging mechanism of DHSCs, K(+) are inserted into the V(2)O(5) negative while 
      OH(-) react with Ni(OH)(2) positive; during discharge, the K(+) and OH(-) are 
      released from V(2)O(5) negative and Ni(OH)(2) positive, respectively, and return 
      back to the electrolyte, which is quite different from traditional metal ion or 
      alkaline supercapacitors. Because of the merits combining dual-ion mechanism and 
      HSCs, the DHSC displays excellent capacity retention of  approximately  81.4% after 10,000 
      cycles, high energy density of  approximately  25.4 muWh cm(-2) and high power density of  approximately  4.66 
      mW cm(-2), indicating the potential applications in the further on flexible 
      wearable electronics.
