文章摘要：
The development of flflexible energy storage devices for portable and wearable electronics has aroused increasing interest. In this work, three-dimensional hierarchical NiCo2O4@NiMn-LDH nanowire/ nanosheet arrays have been successfully fabricated on carbon cloth through a facile hydrothermal and calcination synthetic method. Benefifiting from the sophisticated hybrid nanoarchitectures with desirable structure and components, the optimized NiCo2O4@NiMn-LDH hybrid electrode is found to deliver a remarkable specifific capacity of 278 mA h g−1at 2 mA cm−2and a good rate capability of 89.1% retention at 20 mA cm−2. Detailed analysis of the reaction kinetics for the hybrid electrode clearly indicates the dominant diffffusion-controlled contribution to the total capacity. In addition, a flflexible solid-state hybrid supercapacitor is assembled by taking NiCo2O4@NiMn-LDH and activated carbon as the cathode and anode, respectively, which manifests a maximum energy density of 47 W h kg−1at a power density of 357 W kg−1as well as an excellent long-term cycling stability (95.6% retention after 5000 cycles over 8 mA cm−2). Our work demonstrates the great potential of this core/shell hybrid nanostructure as an advanced battery-type electrode for high-performance flflexible energy storage devices.
