Interlayer Expanded MoS2/Nitrogen-Doped Carbon Hydrangea Nanoflowers Assembled on Nitrogen-Doped Three-Dimensional Graphene for High-Performance Lithium and Sodium Storage

Abstract: A combination of optimization methods has been developed to help compensate for the weak points of molybdenum disulfide (MoS2), including poor electronic conductivity and large volume expansion, for better exhibiting its advantages such as high capacity and stability in the fields of lithium/sodium-ion batteries (LIBs/SIBs). In the study, nitrogen-doped three-dimensional graphene supporting MoS2 hydrangea nanoflowers with a nitrogen-doped carbon intercalation (MoS2/NC@N3DG) hierarchical composite has been desi… Show more

“…Functional carbon nanospheres with controllable size, surface area, pore diameter, surface morphology, and chemical composition are an appealing topic. They reveal enhanced performance in a wide variety of applications, such as electrode materials for electrochemical energy storage, absorbents, or catalysts (Zheng et al, 2014;Wang et al, 2021). Graphene spheres and reshaped structures with good chemical and mechanical properties are among the most promising candidates to overcome the obstacles associated with 2D nanosheets.…”

“…At the same time, the shielding shell is expected to possess high capacity, excellent cycling stability, fast ion transfer rate, and rich active sites for ion adsorption or intercalation. MoS 2 , a type of 2D layered transition-metal dichalcogenides (LTMDs), can be selected as the protective layer for MXenes due to the rich electrochemically active sites, convenient electrolyte ion-transport channels, and high theoretical capacity. , And MoS 2 can exhibit high desalination capacity for the pseudocapacitive ion intercalation process. However, MoS 2 nanosheets tend to aggregate into a big cloud under the action of high surface energy between interlayers and van der Waals interactions .…”

“…The normal dual anode materials for LIBs and SIBs are transition metal oxides (TiO 2 , 5 Fe 3 O 4 , 6 ZnO, 7 NiO, 8 Fe 2 O 3 , 9 Co 3 O 4 , 10 GeMn 2 O 4 11 and sulfides (MoS 2 , 12 FeS 2 , 13 NiS 2 and CoS 2 14 ). At the same time, as a kind of conversion material, metal selenides (NiSe x , 15 NbSe 2 , 16 MnSe 1,17 and MnSe 2 18 ) shows higher volume capacity and rate performance than oxide or sulfide due to its large volume density and a small band gap, and is also a strong competitor as dual anode materials.…”
