“…2H-MoS 2 powders were synthesized using hydrothermal process as per our previous work [47]. Further, for the hydrothermal synthesis of MoS 2 /GO hybrid powders, several GO dispersions were prepared by dissolving different weight percentages of GO (0.5%, 1.5%, 2.5%, and 4.5%) in 5 ml of distilled water.…”

Currently, 2D nanomaterials-based RRAMs are explored on account of their tunable material properties enabling fabrication of low power and flexible RRAM devices. In this work, hybrid MoS2-GO based active layer RRAM devices are investigated. A facile hydrothermal co-synthesis approach is used to obtain the hybrid materials and a cost-effective spin coating method adopted for the fabrication of Ag/MoS2-GO/ITO RRAM devices. The performance of the fabricated hybrid active layer RRAM device is analysed with respect to change in material properties of the synthesized hybrid material. The progressive addition of 0.5, 1.5, 2.5 and 4.5 weight % of GO to MoS2, results in a hybrid active layer with higher intermolecular interaction, in the case of Ag/MoS2-GO4.5/ITO RRAM device, resulting in a unipolar resistive switching RRAM behavior with low SET voltage of 1.37 V and high Ion/Ioff of 200 with multilevel resistance states. A space charge limited conduction (SCLC) mechanism is obtained during switching, which may be attributed to the trap states present due to functional groups of GO. The increased number of conduction pathways on account of both Ag+ ions and oxygen vacancies (Vo 2+), participating in the formation of conducting filament, results in higher Ion/Ioff. This is the first report of unipolar Ag/MoS2-GO/ITO RRAM devices, which are particularly important in realizing high density crossbar memories for neuromorphic and in-memory computing as well as enabling flexible 2D nanomaterials-based memristor applications.

Active sites, mass loading, and Li‐ion diffusion coefficient are the benchmarks for boosting the areal capacity and storage capability of electrode materials for lithium‐ion batteries. However, simultaneously modulating these criteria to achieve high areal capacity in LIBs remains challenging. Herein, MoS2 is considered as a suitable electroactive host material for reversible Li‐ion storage and establish an endogenous multi‐heterojunction strategy with interfacial Mo−C/N−Mo‐S coordination bonding that enables the concurrent regulation of these benchmarks. This strategy involves architecting 3D integrated conductive nanostructured frameworks composed of Mo2C‐MoN@MoS2 on carbon cloth (denoted as C/MMMS) and refining the sluggish kinetics in the MoS2‐based anodes. Benefiting from the rich hetero‐interface active sites, optimized Li adsorption energy, and low diffusion barrier, C/MMMS reaches a mass loading of 12.11 mg cm−2 and showcases high areal capacity and remarkable rate capability of 9.6 mAh cm−2@0.4 mA cm−2 and 2.7 mAh cm−2@6.0 mA cm−2, respectively, alongside excellent stability after 500 electrochemical cycles. Moreover, this work not only affirms the outstanding performance of the optimized C/MMMS as an anode material for supercapacitors, underscoring its bifunctionality but also offers valuable insight into developing endogenous transition metal compound electrodes with high mass loading for the next‐generation high areal capacity energy storage devices.

In recent years, there have been significant advancements in Al‐ion battery development, resulting in high voltage and capacity. Traditionally, only carbon‐based materials with layered structures and strong bonding capabilities can deliver superior performance. However, most other materials exhibited low discharge voltages of 1.4 V, especially in aqueous Al‐ion battery systems lacking anion intercalation. Thus, the development of high‐voltage cathode materials has become crucial. This study introduces 2D MoS2 as a high‐performance cathode for aqueous Al‐ion batteries. The material's interlayer structure enables the intercalation of AlCl4− anions, resulting in high‐voltage intercalation. The resulting battery achieved a high voltage of 1.8 V with a capacity of 750 mAh g−1, contributing to a high energy density of 890 Wh kg−1 and an impressive retention rate of ≈100% after 200 cycles. This research not only sheds light on the high‐voltage anion‐intercalation mechanism of MoS2 but also paves the way for the further development of advanced cathode materials in the field of Al‐ion batteries. By demonstrating the potential of using 2D MoS2 as a cathode material, this finding can lead to the development of more efficient and innovative energy storage technologies, ultimately contributing to a sustainable and green energy future.
