Summary: In this study, a two-dimensional Ti2CTx with expanded interlayer was designed as an anode material for Na-ion batteries by intercalation of dimethyl sulfoxide. The interlayer-expanded Ti2CTx exhibited a higher initial discharge capacity of 486 mAh g(-1) and maintained a stable capacity of 176 mAh g(-1) after 250 cycles at 100 mA g(-1), compared to the pristine Ti2CTx.

Summary: By anchoring oxygen-incorporated MoS2 nanoflower on graphene, the expanded interlayer spacing allows simultaneous intercalation/deintercalation of Mg2+ and Li+ into/from the host material. This configuration effectively reduces diffusion barrier of metal ions, increases intercalated number of ions, and enhances structure stability. Furthermore, intercalated Li+ boosts the intercalation kinetics of Mg2+, leading to superior rate capability and cycling performance of the O-MoS2/G with high reversible capacity after 2000 cycles.

Summary: By using density functional theory calculation method, the effect of interlayer distance on sodium ion storage in pure EG was investigated. The results showed that within the range of 4.4 angstrom to 6.0 angstrom, EG can store a significant amount of sodium ions through an intercalation mechanism, forming a stable sodium-graphite intercalation compound.

Summary: The study successfully synthesized a highly stable MoS2-O nanosphere with intercalated Mo-O bonds as a cathode material for Zn ion batteries. The sulfidation degree expanded the interlayer spacing of MoS2, while the intercalated Mo-O bonds enhanced the structural integrity and stability of the fabricated cathode during Zn insertion/extraction cycles. This optimized structure significantly improved the specific capacity and cycling stability of ZIBs with MoS2-O nanosphere cathode over 300 cycles, showing promise for enhancing the capacity retention performance of MoS2 in ZIBs.

Summary: To simplify the synthesis of interlayer-expanded MoS2 (E-MoS2), a reactant conversion-intercalation strategy is developed using ammonium thiocyanate as the intercalator. The obtained E-MoS2 exhibits superior supercapacitor performance with high specific capacity and energy density. The favorable electrochemical performance is attributed to the expanded interlayer spacing and the large Na+ adsorption capacitance. This work provides a novel intercalation strategy for the development of high-performance electrode materials for energy applications.
