Exploring robust electrode materials which could permit fast and reversible insertion/extraction of large K+ is a crucial challenge for potassium-ion batteries (PIBs). Smart interfacial design facilitate charge transport as well assure the integrity electrode. Herein, Cetyltrimethylammonium bromide (CTAB) was found to play bifunctional roles in construction Nb2CTx@MoSe2 heterostructure. Firstly, functionalization CTAB on surface Nb2CTx influence subsequent growth MoSe2 by electrostatic effect, stereochemical effect synergetic Lewis acid-base interaction, leading formation with tiled Secondly, interlayer spacing expanded from 0.77 1.21 nm owing pillar CTAB. As excepted, capacity (406 mA h g-1) retention 80% 100 g-1 1000 concerning rate capability specific maintains at 240 (at 2000 over 300 cycles. The calculated DK values (from GITT measurement) titled C-T-Nb2CTx@MoSe2@C two orders magnitude larger than traditional T-Nb2CTx@MoSe2@C electrode, further confirming intimate interface between provide convenient channels diffusion kinetics. Finally, ex-situ characterizations different charging discharging voltage stages, including XRD/Raman/HRTEM/XPS, have been carried out reveal potassium storage mechanism This work provides facile strategy regulation engineering assist extend other MXenes-TMCs hybrid electrodes.

Abstract The inevitable shuttling and slow redox kinetics of lithium polysulfides (LiPSs) as well the uncontrolled growth Li dendrites have strongly limited practical applications lithium‐sulfur batteries (LSBs). To address these issues, we innovatively constructed carbon nanotubes (CNTs) encapsulated Co nanoparticles in situ grown on TiN‐MXene nanosheets, denoted TiN‐MXene‐Co@CNTs, which could serve simultaneously both sulfur/Li host to kill “three birds with one stone” (1) efficiently capture soluble LiPSs expedite their conversion, (2) accelerate nucleation/decomposition solid 2 S, (3) induce homogeneous deposition. Benefiting from synergistic effects, TiN‐MXene‐Co@CNTs/S cathode a sulfur loading 2.5 mg cm −2 show high reversible specific capacity 1129.1 mAh g −1 after 100 cycles at 0.1 C, ultralong cycle life over 1000 1.0 C. More importantly, it even achieves areal 6.3 50 under 8.9 low E/S ratio 5.0 μL . Besides, TiN‐MXene‐Co@CNTs deliver stable plating/striping behavior h.

The severe shuttle effect and the depletion of active sulfur result in performance deterioration, presenting two formidable issues that must be overcome to achieve high-mass-loading lithium–sulfur batteries. Herein, we reported a composite separator by introducing carbon photonic crystals with hierarchically ordered porous structure on commercial separator. interconnected hierarchical macro–meso–micropore network facilitate efficient trapping polysulfides rapid transport lithium ions. high ion diffusivity promotes conversion enhancing utilization mitigating occurrence "dead sulfur" surface Impressively, under loading 3 mg cm–2, battery displayed reversible capacity 1582 mA h g–1 at 0.1 C an excellent long-term cycling decay rate as low 0.033% per cycle over 1500 cycles 1 C.
