Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In this work, self‐supporting three‐dimensional hierarchical nanostructured MoS₂@Ni(OH)₂ nanocomposites are synthesized via a facile single‐mode microwave hydrothermal technique. The fabricated MoS₂@Ni(OH)₂ nanocomposites for supercapacitors in aqueous electrolyte exhibit higher specific capacitance and better cyclic stability than those of MoS₂ and Ni(OH)₂ due to the pronounced synergistic effect between MoS₂ and Ni(OH)₂. Further, the flexible all‐solid‐state supercapcitor is readily constructed by composing the PVA/KOH gel electrolyte in between two MoS₂@Ni(OH)₂ electrodes on the flexible PET substrates. The resulting supercapacitors can operate at high rate up to 1000 V/s, have excellent long‐life cycling stability, retaining 94.2% of the initial capacitance after 9000 cycles, and mechanical flexibility during extreme bending, respectively. Thereby, the MoS₂@Ni(OH)₂ nanocomposites are a promising electrode materials for flexible long‐life cycling all‐solid‐sate supercapacitors.</p> </abstract>
