One-pot synthesize high stable carbon-MoS2 nano-sphere electrodes by co-growth mechanism for supercapacitors

Abstract

In order to enhance the capacity and stability of supercapacitor electrode at high current density, the cabon-MoS2 nano-sphere is prepared in one-pot by co-growth mechanism. With the help of co-growth mechanism, the part of MoS2 is embedded in carbon supporter, which makes two components well-combined. Besides increases the stability, the carbon supporter also helps decrease the impedance of composite electrode. As the result, the composite materials show high specific capacitance (1000 F g-1 at 1 A g-1) and wonderful stability (capacity retention rate as 93%) at large current density (20 A g-1) for long cycle life (20000 cycles). When the carbon-MoS2//AC-ASC is fabricated, it demonstrates high energy density of 32 Wh kg-1 when the power density reaches 224.58 Wk g-1, revealing the viability and potential for practical applications.
