High-performance transparent and stretchable all-solid supercapacitors based on highly aligned carbon nanotube sheets.

ABSTRACT: By using highly aligned carbon nanotube (CNT) sheets of excellent optical transmittance and mechanical stretchability as both the current collector and active electrode, high-performance transparent and stretchable all-solid supercapacitors with a good stability were developed. A transmittance up to 75% at the wavelength of 550 nm was achieved for a supercapacitor made from a cross-over assembly of two single-layer CNT sheets. The transparent supercapacitor has a specific capacitance of 7.3 F g(-1) and can be biaxially stretched up to 30% strain without any obvious change in electrochemical performance even over hundreds stretching cycles.
