“…Besides, the sharp cathodic peak near 0.1 V can be ascribed to the intercalation of Na + into Ti 3 C 2 T x and NC [36] . From the second scan onwards, no sharp cathodic peak can be found; two broad peaks in the voltage ranges of 1.6–2.0 and 0.4–0.8 V correspond to the intercalation reaction between MoS 2 and Na + with the formation of Na x MoS 2 and subsequent conversion reaction [37] . In regard to the anodic scan, a slight peak from 0.7 to 1.1 V and a broad peak from 1.6 to 1.9 V correspond to the reversible oxidation process [26] .…”

Although it is a promising sodium storage material due to its excellent electrochemical activity, small bandgap, and large interlayer spacing, layered molybdenum disulfide (MoS2) suffers from poor rate capability and degraded cycling life, resulting from its serious aggregation upon preparation, sluggish reaction kinetics, and structure expansion during cycling. To address these issues, a polyethyleneimine (PEI)‐assisted fabrication approach was developed for the rational synthesis of an interconnected framework with nitrogen‐doped carbon‐confined MoS2 nanosheets/Ti3C2Tx MXene (MoS2/Ti3C2Tx@NC), where the PEI could guide the uniform growth of MoS2 on Ti3C2Tx and the self‐generated NC simultaneously enhanced its synergistic coupling with MoS2/Ti3C2Tx, thus contributing to the improvement of charge transfer, diffusion kinetics, and structural integrity of the hybrid electrode. Consequently, the desired MoS2/Ti3C2Tx@NC delivered impressive sodium storage performance, demonstrating high reversible capacities of 397.3 and 206.8 mAh g−1 at 0.1 A g−1 after 100 cycles and 0.5 A g−1 after 500 cycles, respectively. Moreover, electrochemical kinetics analysis and charge storage mechanism manifested that high capacitive contribution, facilitated Na+ transport pathways, and synergistic electronic coupling between MoS2/Ti3C2Tx and NC contributed to the superior sodium storage performance.

“…Further compared with literature reported MoS 2 for SIBs, amorphous MoS 3 ‐on‐rGO still exhibits remarkable rate‐cycle performance, as shown in Figure S21 (Supporting Information). [ 27–29,57,72–76 ] Furthermore, we explored a sodium‐ion full cell (SIFC) to pave the way for the practical application of amorphous MoS 3 anode. The coupled cathode is 3D flower‐like structured Na 3 V 2 (PO 4 ) 3 (material characterizations displayed in Figure S22, Supporting Information), showing a high voltage platform of around 3.4 V (Figure S23, Supporting Information).…”

Beyond‐lithium‐ion storage devices are promising alternatives to lithium‐ion storage devices for low‐cost and large‐scale applications. Nowadays, the most of high‐capacity electrodes are crystal materials. However, these crystal materials with intrinsic anisotropy feature generally suffer from lattice strain and structure pulverization during the electrochemical process. Herein, a 2D heterostructure of amorphous molybdenum sulfide (MoS3) on reduced graphene surface (denoted as MoS3‐on‐rGO), which exhibits low strain and fast reaction kinetics for beyond‐lithium‐ions (Na+, K+, Zn2+) storage is demonstrated. Benefiting from the low volume expansion and small sodiation strain of the MoS3‐on‐rGO, it displays ultralong cycling performance of 40 000 cycles at 10 A g−1 for sodium‐ion batteries. Furthermore, the as‐constructed 2D heterostructure also delivers superior electrochemical performance when used in Na+ full batteries, solid‐state sodium batteries, K+ batteries, Zn2+ batteries and hybrid supercapacitors, demonstrating its excellent application prospect.

“…[32,33,43,44] In order to further investigate the phase transformation process or Li + insertion under different cutoff voltages, the energetic convex hull with the pseudobinary phase diagram of MoS 2 and Li below the convex hull has also been conducted. [45] In Figure 1f, the LiMoS 2 with a formation energy of −0.0662 eV atom −1 demonstrates to be the most stable phase compared to the other phases of Li 2.5 MoS 2 and Li 3 MoS 2 , respectively. Simultaneously, the calculated voltage plateau for LiMoS 2 is 1.1 V (Figure 1d), corresponding well to the cyclic voltammetry (CV) curve (Figure 1b; Figure S1, Supporting Information) and discharge curve (Figure 1c) of TiN/2H-MoS 2 .…”

Accelerating the conversion of polysulfide to inhibit shutting effect is a promising approach to improve the performance of lithium–sulfur batteries. Herein, the hollow titanium nitride (TiN)/1T–MoS2 heterostructure nanospheres are designed with efficient electrocatalysis properties serving as a sulfur host, which is formed by in situ electrochemical intercalation from TiN/2H‐MoS2. Metallic, few‐layered 1T‐MoS2 nanosheets with abundant active sites decorated on TiN nanospheres enable fast electron transfer, high adsorption ability toward polysulfides, and favorable catalytic activity contributing to the conversion kinetics of polysulfides. Benefiting from the synergistic effects of these favorable features, the as‐developed hollow TiN/1T‐MoS2 nanospheres with advanced architecture design can achieve a high discharge capacity of 1273 mAh g−1 at 0.1 C, good rate performance with a capacity retention of 689 mAh g−1 at 2 C, and long cycling stability with a low‐capacity fading rate of 0.051% per cycle at 1 C for 800 cycles. Notably, the TiN/1T‐MoS2/S cathode with a high sulfur loading of up to 7 mg cm−2 can also deliver a high capacity of 875 mAh g−1 for 50 cycles at 0.1 C. This work promotes the prospect application for TiN/1T‐MoS2 in lithium–sulfur batteries.
