Abstract: | Stretchable supercapacitors that can sustain their performance under unpredictable tensile force are important elements for practical applications of various portable and wearable electronics. However, the stretchability of most reported supercapacitors was often lower than 100 % because of the limitation of the electrodes used. Herein we developed all‐solid‐state supercapacitors with a stretchability as high as 240 % by using aligned carbon nanotube composites with compact structure as electrodes. By combined with pseudocapacitive molybdenum disulfide nanosheets, the newly developed supercapacitor showed a specific capacitance of 13.16 F cm?3, and also showed excellent cycling retention (98 %) after 10 000 charge–discharge cycles. This work also presents a general and effective approach in developing high‐performance electrodes for flexible and stretchable electronics. |
