Abstract
Flexible energy storage technologies play a crucial role in powering portable and wearable technologies for monitoring physical indicators in various biomedical applications. Composite nanomaterials based on two-dimensional materials are currently employed to enhance the efficiency of flexible energy storage systems. In this study, a hybrid nanocomposite, CNT/ZnS-NbS2, is synthesized through a hydrothermal process. The CNT/ZnS-NbS2 exhibits an outstanding 1107C/g capacity in a three-cell configuration. The CNT/ZnS-NbS2 nanocomposite is used to construct flexible supercapacitor (FSC) electrodes. When evaluated in a full-cell architecture with activated carbon, CNT/ZnS-NbS2 produce an energy density equal to 53 Wh/kg. The CNT/ZnS-NbS2 electrode also demonstrated an overpotential of 221 mV in HER applications. These results illustrate the potential of the flexible energy storage system to be coupled with hydrogen evolution reaction.
