Nitrogen‐Doped Core‐Sheath Carbon Nanotube Array for Highly Stretchable Supercapacitor

A highly stretchable supercapacitor is developed from a family of nitrogen-doped core-sheath carbon nanotube array as an elastic electrode. It displays a specific capacitance of 30.8 mF cm−2 with the strain up to 400%; the specific capacitance can be maintained by 96% after stretching for 1000 cycles. The unique 3D cross-linked structure in the elastic electrode contributes to the high property.
