MoS2 /C composites constructed with van der Waals forces have been extensively applied in lithium-sulfur (Li-S) batteries. However, the catalytic conversion effect on polysulfides is limited because weak electronic interactions between composite interfaces cannot fundamentally improve intrinsic conductivity of . Herein, density functional theory calculations reveal that and nitrogen-doped carbon an Mo-O-C bond can promote a Gibbs free energy only 0.19 eV low dissociation barrier 0.48 eV,...
Rational nanoscale surface engineering of electroactive nanoarchitecture is highly desirable, since it can both secure high surface‐controlled energy storage and sustain the structural integrity for long‐time high‐rate cycling. Herein, ultrasmall MoS 2 quantum dots (QDs) are exploited as sensitizers to boost electrochemical properties Li 4 Ti 5 O 12 (LTO). The LTO/MoS composite prepared by anchoring 2D LTO nanosheets with QDs using a simple effective assembly technique. Impressively, such...

Abstract Li metal batteries have been widely expected to break the energy‐density limits of current Li‐ion batteries, showing impressive prospects for next‐generation electrochemical energy storage system. Although much progress has achieved in stabilizing anode, electrode still lacks efficiency and safety. Moreover, a practical battery requires thickness‐controllable maximally balance density stability. However, due stickiness fragile nature metal, manufacturing ingot into thin electrodes...
Lithium–sulfur (Li–S) batteries have been considered a promising next-generation energy storage device. However, the serious polysulfide shuttle effect and slow reaction kinetics hampered their development. Herein, alkylamine-tuned MoOx with synergistic manipulation of interlayer spacing oxygen vacancies as bifunctional mediator for separator modification (refer to MOC/PP) in Li–S is proposed. The increased provides rapid stable pathway Li+ diffusion, facilitating uniform deposition on...
