Abstract Scope |
Stretchable electronics have received increasing attention due to their broad applications in emerging wearable devices, biomedical devices, epidermal electronics and biointegrated electronics. To integrate stretchable electronics into a power-independent stretchable system in an elegant way, stretchable energy conversion/storage devices become of paramount importance. We proposed a new type of highly stretchable and reliable supercapacitor based on crumpled vertically aligned carbon nanotube (CNT) forests transferred to an elastomer substrate. The stretchable SCs consist of two crumpled CNT forest electrodes and one solid-state electrolyte layer of PVA-KCl, which also serves as a separator for the SC. The crumpled CNT-forest electrodes have two major advantages: (1) CNT forests are very stable and can be easily patterned by annealing-assisted contact transfer, and (2) the vertical CNT forests have a larger surface area compared to a conventional thin flat film and can be easily modified to be hybrid SCs, particularly in the crumpled states. |
