Ultrafast supercapacitors based on heterostructured 2D nanocomposite film of graphene/MoS2 nanosheets |
| 초록 |
An industrially adoptable fluid dynamic exfoliation process is reported to produce large quantities of ionic liquid (IL)-functionalized metallic phase MoS2 (m-MoS2) and defectfree graphene (Gr) sheets. Hybrid 2D–2D layered films are also fabricated by incorporating Gr sheets into compact m-MoS2 films, resulting in an outstanding volumetric capacitance of 1430.5 F cm−3 at 1 A g−1 and an extremely high rate capability of 80% retention at 1000 A g−1. The flexible supercapacitor assembled using a polymer-gel electrolyte exhibits excellent resilience to harsh electrochemical and mechanical conditions while maintaining an impressive rate performance and long cycle life. Successful achievement of an ultrahigh volumetric energy density (1.14 W h cm−3) using an organic electrolyte with a wide cell voltage of ≈3.5 V is demonstrated. |
