AB  - The novel carbon (C)/MnO2 double-walled nanotube arrays (DNTAs) are designed and 
      fabricated via template-assisted electrodeposition. The unique DNTA architectures 
      of C/MnO2 composites with high weight fraction of MnO2 allow high electrode 
      utilization ratio and facilitate electron and ion transmission. In the half-cell 
      test, the hybrid C/MnO2 DNTAs as electrodes show a large specific capacitance 
      (Csp) of 793 F/g at the scan rate of 5 mV/s, high energy/power densities, and 
      much enhanced long-term cycle stability. After 5,000 cycles, the Csp retention of 
      C/MnO2 DNTAs keeps  approximately 97%, which is much larger than 69% of the MnO2 nanotube 
      arrays (NTAs). The symmetrical supercapacitors (SSCs) composed of C/MnO2 DNTAs 
      also show the predominant performance, such as large Csp of 161 F/g and high 
      energy density of  approximately 35 Wh/kg, indicating that the C/MnO2 DNTAs is a potential 
      electrode for supercapacitors. The high order pore passages, double-walled 
      structures, hollow structures, and high conductivity are responsible for the 
      superior performance of C/MnO2 DNTAs. Such hybrid C/MnO2 DNTAs may bring new 
      opportunities for the development of supercapacitors with superior performance.
