An integrated self-charging power system incorporating flexible fiber-shaped coaxial asymmetric supercapacitors (FASCs) with flexible triboelectric nanogenerators (FTENGs) has the potential to harvest and store energy simultaneously for achieving self-charged power pack. In this study, we develops a new strategy for fabricating a metal-organic framework (MOF) for the template-directed growth of hierarchically well-oriented nanowire arrays based on carbon nanotube fibers (CNTFs) for electrochemical supercapacitors. Uniform [email protected]₂O₄@Zn-Co-S hybrid arrays (HAs) derived from a zinc/cobalt-based zeolitic imidazolate framework (Zn/Co-ZIF) are first fabricated via a facile annealing and sulfuration process and a [email protected]₃O₄@CoNC HA derived from a Co-based MOF is synthesized via oxidation and carbonization processes; the products act as positive and negative electrodes respectively in the assembled FASCs. The as-prepared [email protected]₂O₄@Zn-Co-S HAs and [email protected]₃O₄@CoNC HAs are endowed with rich reaction sites, a facile ion diffusion path, and improved conductivity because of their unique hierarchical structure and good synergistic effect, which improves the electrochemical properties of the MOF derivatives. In addition, the assembled FASCs device exhibits a remarkable electrochemical performance with excellent rate capability. This study provides a strategy for the rational design of hierarchically structured, well-oriented MOFs and derivative arrays with high electrochemical performance and mechanical flexibility. Moreover, the flexible fiber-shaped MOF–derivative HA asymmetric supercapacitor is charged by a flexible triboelectric nanogenerator, demonstrating the promise of an self-charging power pack that has considerable potential for developing flexible multifunctional electronic devices.
