Abstract

Flexible and stretchable electronics have attracted extensive attention and research efforts recently. As an indispensible component, energy storage device thai is able to bear large mechanical strain and be integrated with the stretchable electronics makes the whole system stretchable. Here we report reversibly stretchable supercapacitors using buckled single-walled carbon nanotube (SWNT) macro-films as the electrodes, which have controllable wavy geometries and show extremely high mechanical stretchability with the utility of polydimethylsiloxane (PDMS) as the elastomeric substrates. The stretchable supercapacitors exhibit very stable capacitance under cyclic stretching and releasing, and comparable energy and power densities with those using pristine SWNT macro-films as electrodes.
