“…The CNF/G matrix shows a broad diffraction peak at about 26.1°, which corresponds to the (002) crystal diffraction of the carbon materials. − The SSC@SnS 2 aerogel exhibits diffraction peaks at 14.9°, 28.5°, 32.3°, and 50.3°, corresponding to the (001), (100), (101), and (110) phases as that of pure SnS 2 (JCPDS card no. 23-0677), ,− respectively. Here, the (001) diffraction peak of SSC@SnS 2 that located at 2θ = 14.8° indicates an interlayer spacing of 5.9 Å, which allows the efficient insertion and extraction of sodium ions. , Here, the diffraction peak intensity of SSC@SnS 2 is a little weaker than that of the pure SnS 2 , which is possibly due to the porous morphology of the SSC@SnS 2 aerogel and the uniform dispersion of SnS 2 nanoflakes.…”

Developing high-performance electrode materials with high energy and long-term cycling stability is a hot topic and of great importance for sodium ion batteries (SIBs). In this work, a highly porous carbon/tin sulfide aerogel with a “skeleton/skin” morphology (SSC@SnS2) has been developed and further used as a binder-free anode for SIBs. This SSC@SnS2 electrode delivers a high specific capacity of 612 mA h g–1 at 0.1 A g–1, a good rate capability, and a long-term cycling stability up to 1000 times with an average Coulombic efficiency of ∼99.9%. Meanwhile, this SSC@SnS2 aerogel also achieves a stable cycling performance even at a high current density up to 5.0 A g–1. The fast-yet-stable sodium ion storage performance of the prepared SSC@SnS2 aerogel can be ascribed to the reasons that (i) the carbon nanofiber/graphene skeleton provides unimpeded pathways for the rapid transfer of electrons; (ii) thin SnS2 skin with nonaggregated morphology can provide a great number of active sites for sodium ion storage; (iii) the porous structure of the SSC@SnS2 aerogel ensures a rapid penetration of electrolyte and can further accommodate the volume expansion of active SnS2 nanoflakes; and (iv) the intermediate product of Na15Sn4 alloy contributes greatly to the sodium ion storage performance of the SSC@SnS2 aerogel. The excellent electrochemical performances coupling with the unique structural features of this SSC@SnS2 aerogel make it a promising anode candidate for SIBs.

“…Its overall water splitting performance as a bi-functional catalyst is better than that of recently reported catalysts, as shown in Table 9. † 60,61 The overall water splitting voltage of LSC/MoS 2 remains at about 1.48 V aer continuous operation at 10 mA cm −2 and 1.88 V at 100 mA cm −2 for 22 h, which demonstrates that its stability is better than that of Pt/C‖RuO 2 in Fig. 7d.…”

“…Nevertheless, the inherent low conductivity still exists. The pivotal to addressing this issue is to rationally hybridize with high conductive carbon, popularly loading 2D nanosheets on various carbon substrate [20][21][22], such as ultrathin MoS 2 nanosheets supported on N-doped hollow carbon nanobox [23], MnO 2 nanosheets distributed on hollow carbon nanospheres [24]. An extensive cycling will unavoidably cause the structural pulverization although these hybrids exhibit high specific capacity because the thin carbon layer microsubstrate is difficult to afford the repeated structural change after a long charge/discharge process.…”

Developing novel electrode materials for lithium-ion batteries (LIBs) with rapid charge/discharge capability and high cycling stability remains a big challenge to date. Herein, we demonstrate the design and synthesis of ultrathin MoS 2 nanosheets in-situ grown on sponge-like carbon nanospheres by a simple diffusion-controlled process. The unique sponge-like carbon nanosphere core can be used as "reservoir" of electrolyte by adsorbing to shorten the iondiffusion path, and meanwhile as "elastomer" to alleviate the structural change of the MoS 2 nanosheets during the charge/ discharge processes. Furthermore, the vertical ultrathin MoS 2 nanosheets with broadened interlayer space greatly enrich the electrochemical active sites. Consequently, the as-obtained MoS 2 /C nanospheres exhibit increased specific capacities at various rates with superior cycling stability compared to the MoS 2 /C floccules. It is reckoned that the present concept can be extended to other electrode materials for achieving highrate and stable LIBs.
