“…The four peaks at ≈283.90, 284.26, 285.29, 286.28, and 283.30 eV correspond to the C─C, C═N, C─S, C─N/C─O, and Sn─C bonds. [65] The existence of C─N bond indicated that N atoms were successfully doped into the carbon matrix materials. In addition, the heteroatom doping introduces more lithium-affinitive sites into the carbon matrix, effectively guiding the uniform nucleation of lithium and facilitating highly reversible Li + insertion/extraction processes, which enhances the performance.…”

The development of conversion‐typed anodes with ultrafast charging and large energy storage is quite challenging due to the sluggish ions/electrons transfer kinetics in bulk materials and fracture of the active materials. Herein, the design of porous carbon nanofibers/SnS2 composite (SnS2@N‐HPCNFs) for high‐rate energy storage, where the ultrathin SnS2 nanosheets are nanoconfined in N‐doped carbon nanofibers with tunable void spaces, is reported. The highly interconnected carbon nanofibers in three‐dimensional (3D) architecture provide a fast electron transfer pathway and alleviate the volume expansion of SnS2, while their hierarchical porous structure facilitates rapid ion diffusion. Specifically, the anode delivers a remarkable specific capacity of 1935.50 mAh g−1 at 0.1 C and excellent rate capability up to 30 C with a specific capacity of 289.60 mAh g−1. Meanwhile, at a high rate of 20 C, the electrode displays a high capacity retention of 84% after 3000 cycles and a long cycle life of 10 000 cycles. This work provides a deep insight into the construction of electrodes with high ionic/electronic conductivity for fast‐charging energy storage devices.

“…It should be noticed that metal sulfides present higher electrical conductivity, better mechanical strength, higher thermal stability, and better electrochemical activity in comparison to metal oxide. Furthermore, the electrochemical activity of metal sulfide is better than metal oxide due to the weaker binding energy of M-S than M-O [56].…”

Introducing suitable electrode materials and electrolytes for supercapacitors and next-generation batteries should be considered for the industrial application of these devices. Among the proposed materials for them, transition metal chalcogenide (TMCs), are attractive and efficient options due to their unique properties such as appropriate layered structure, good oxidation state of transition metals, high thermal and mechanical stabilities, etc. However, applying other layered materials with high electrical conductivity e.g. carbon-based materials can lead to producing remarkable results for the mentioned applications. However, an interesting point is how making TMCs composite with different types of carbon materials leads to improve electrochemical and structural properties of TMCs as active materials. In the present short review, the structural and electrochemical improvements of different types of TMC composites with carbon-based materials and their mechanism are investigated for supercapacitors and next-generation rechargeable batteries.

“…Also, the reversible capacity after 30 cycles was 583 mAh g –1 . Wu et al confirmed that the initial charge–discharge specific capacities of the flower-like SnS 2 electrodes prepared by the hydrothermal method were 1296.8 and 529.9 mAh g –1 , respectively, while the initial specific capacity was only 40.87%. The reversible capacity is only 203.7 mAh g –1 after 90 cycles at 0.1 A g –1 .…”

Tin sulfide, as a promising anode material for Li-ion batteries, suffers from high-capacity loss during cycling and low initial Coulombic efficiency, which limits its further application. In order to solve these problems, Li + -intercalated SnS 2 with expanded interlayer spacing (0.89 nm) was prepared by the one-step urothermal method. The successful synthesis of Li + -intercalated SnS 2 is confirmed by means of X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, inductively coupled plasma emission spectrometer test, and exfoliation experiment. Compared with pure SnS 2 , the Li + -intercalated SnS 2 electrode displays a higher initial Coulombic efficiency (79.3%) than the pure SnS 2 electrode (55%). Also, Li + -intercalated SnS 2 exhibits more excellent rate performance (548.4 mAh g −1 at 2 A g −1 and 216.6 mAh g −1 at 10 A g −1 ) and cycling performance (647.7 mAh g −1 at 0.1 A g −1 after 100 cycles).
