Abstract

In the present work, Molybdenum disulfide/ hematite/Graphene (MoS₂/Fe₂O₃/G) composite based heterostructure material is successfully prepared by hydrothermal method and employed as electrode material for supercapacitor device. The electrochemical properties and performance of prepared electrode overruled pure MoS₂ and MoS₂/Fe₂O₃ composite. The MoS₂/Fe₂O₃/G composite electrode delivered significant capacitance of 98.2 mAh g⁻¹ at 1 A g⁻¹ and outstanding cycling behavior. To determine practical application, the MoS₂/Fe₂O₃/G and Activated carbon electrodes are used as cathode and anode material for asymmetric supercapacitor (ASC) design. The ASC device unveiled energy and power density of 46.8 Wh kg⁻¹ and 750 W kg⁻¹. Moreover, the device retained the capacity up to 77% even after 10,000 cycles. Thus, the MoS₂/Fe₂O₃/G electrode material can be claimed to have constructive prospect for practical application of supercapacitor.
