Recently, Wang Qi from the Institute of Plasma Physics, Chinese Academy of Sciences, and Han Min, a professor from Nanjing Normal University collaborated on the large-scale preparation of high-performance heteroatom-doped graphene-based nanostructures and their applications in flexible all-solid state Super capacitor applications made new progress. Some of the research results have been published online in the International Journal Small, and was selected as the magazine's InsideFrontCover. In order to meet the growing demand for flexible wearable electronic products, there is an urgent need to develop flexible all-solid-state power sources or energy storage devices. To achieve this goal, the key is to design and develop both excellent energy storage and mechanical properties of the electrode material. The appearance of heteroatom-doped graphene and 2D layered metal sulfide (LMCs) nanostructures has brought new opportunities for the design of high-performance electrode materials. However, the energy storage properties (energy density, cycle stability, etc.) Need to be further improved. Whether these two types of materials can be effectively "married" or coupled to develop high performance electrode materials is still a challenging topic in the field of materials science and chemistry. In response to the above problems, Wang Qi and Han Min research group conducted a cooperative study to utilize the strategy of heat-controlled conversion of oleylamine-SnS2-SnS hybrid nanodisk precursors to cleverly convert organic molecules to carbonization, doping, phase inversion and Self-assembly and other important physical and chemical processes integrated in one, the first successful realization of sulfur-doped graphene (SG) and SnS hybrid nanosheets in situ synthesis and assembly, has been a novel 3D porous SnS / SG hybrid nanostructures (HNAs, as shown in Figure 1). Compared with the traditional synthesis strategy, the method has the advantages of simple and efficient, good reproducibility and large scale preparation, which lays the foundation for extending and expanding the application of doped graphene materials in important technologies such as clean energy, optoelectronics and sensing . In the three-electrode system with KOH solution as the electrolyte, the obtained 3D graphene composite has a mass specific capacitance up to 642Fg-1 (current density of 1Ag-1), much higher than the recently reported graphene composite and other electroactive materials Such as bulk and nanoscale SnS and its composites, G-Mn3O4 nanorods, G-CoS2, 2DCoS1.07 / NC nanocomposites, etc.). Subsequently, ASSSCs, a flexible all-solid-state supercapacitor device, was further developed to demonstrate excellent electrochemical energy storage performance with an area specific capacitance of up to 2.98 mFcm-2, excellent long-term cycle stability (99% for 10000 cycles), excellent flexibility and mechanical Stability (more than 1000 folds repeated or fold with no change in properties) outperformed the reported graphene, 2DSnSe2 and SnSe, and 3DGeSe2 nanostructure-based flexible ASSSCs. This work proposed a new strategy for in-situ integration and assembly of 2D nanostructured units to construct 3D porous hybrid nanostructured or framework materials with the promise of large-scale preparation for the rational design of high-performance hybrid electrode materials for future development Flexible power sources or energy storage devices pave the way. In addition, through the optimized design and combination, it is expected to extend other types of multi-functional 3D porous framework material, the follow-up work is ongoing.
