| description | The microflower-like Si/MoS<sub>2</sub> composites were fabricated using Si quantum dots (QDs) to assist a facile hydrothermal method. The electrochemical performance of Si/MoS<sub>2</sub> composite in symmetric and asymmetric systems was studied. Electrochemical characterization revealed that the Si/MoS<sub>2</sub> composite electrode in a three-electrode system has a high specific capacitance of 574.4 F·g<sup>−1</sup> at 5 A·g<sup>−1</sup>. Furthermore, the Si/MoS<sub>2</sub> composite electrode in a two-electrode system had the maximum energy density of 27.2 Wh·kg<sup>−1</sup> when a power density of 749.1 W·kg<sup>−1</sup> was achieved. Therefore, this investigation proves the Si/MoS<sub>2</sub> composite microflower-like structure should be a promising candidate electrode material for supercapacitors. |
