ABSTRACT=<p>Molybdenum disulfide/reduced graphene oxide/polyaniline ternary composites (MoS<sub>2</sub>/rGO/PANI) were designed and synthesized by a facile two-step approach including hydrothermal and <italic>in situ</italic> polymerization process. The MoS<sub>2</sub>/rGO/PANI composites presented an interconnected 3D network architecture, in which PANI uniformly coated the outer surface of the MoS<sub>2</sub>/rGO binary composite. The MoS<sub>2</sub>/rGO/PANI composites with a weight percent of 80% (MGP-80) exhibits the best specific capacitance (570 F g<sup>−1</sup> at 1 A g<sup>−1</sup>) and cycling stabilities (78.6% retained capacitance after 500 cycles at 1 A g<sup>−1</sup>). The excellent electrochemical capacitive performance is attributed to its 3D network structure and the synergistic effects among the three components that make the composites obtain both pseudocapacitance and double-layer capacitance.</p>
