Two-dimensional (2D) layered materials have promising prospects for Zn-storage due to their flexible and adjustable interlayer architecture. The strong electrostatic interaction and high diffusion energy barrier, however, lead to slow diffusion kinetics of Zn-ions between the 2D interfaces, limiting its widespread application. Herein, Ti3C2 MXene is introduced into the MoS2 interlayer by the "pillar effect" to assemble a layer-by-layer inter-embedded structure (L-MoS2/Ti3C2), which provides sufficient diffusion channels for Zn-ions. DFT computations and GITT confirm that the L-MoS2/T...

The sluggish diffusion kinetics of divalent Zn2+ in cathode and the limited availability of active material have seriously hindered the practical application of aqueous zinc ion batteries (AZIBs). Herein, multi-walled carbon nanotubes modified by amorphous carbon layer successfully compounded with MoS2 (MWCNTs@a-C@MoS2) are designed as the cathode for AZIBs. Benefiting from the large number of oxygenous groups on the loose surface of amorphous carbon, MoS2 can uniformly nucleate and grow on the MWCNTs, thus avoiding the agglomeration of MoS2 and improving the utilization of active materials. T...

Abstract The effect of grain boundary (GB) defects on the tribological properties of MoS has been investigated by molecular dynamics (MD) simulations. The GB defects-containing MoS during scratching process shows a lower critical breaking load than that of indentation process, owing to the combined effect of pushing and interlocking actions between the tip and MoS atoms. The wear resistance of MoS with GB defects is relevant to the misorientation angle due to the accumulation of long Mo-S bonds around the GBs. Weakening the adhesion strength between the MoS and substrate is an efficient ...
