Abstract Fluorides are viewed as promising conversion‐type Li‐ion battery cathodes to meet the desired high energy density. FeOF is a typical member of fluorides, but its major drawback sluggish kinetics upon deep discharge. Herein, heterostructured FeOF‐MXene composite (FeOF‐MX) demonstrated overcome this limitation. The rationally designed FeOF‐MX electrode features microsphere morphology consisting closely packed nanoparticles, providing fast transport pathways for lithium ions while continuous wrapping network MXene nanosheets ensures unobstructed electron transport, thus enabling high‐rate storage with enhanced pseudocapacitive contribution. In/ex situ characterization techniques and theoretical calculations, both reveal that mechanism in arises from hybrid intercalation‐conversion process, strong interfacial interactions between promote adsorption migration. Remarkably, through demarcating reaction controlled potential window, symmetric full prelithiated cathode anode fabricated, achieving density 185.5 Wh kg −1 impressive capacity retention 88.9% after 3000 cycles at 1 A g . This work showcases an effective route toward high‐performance engineered fluoride‐based electrodes provides new insights into constructing batteries yet high‐energy/power densities.

Abstract With the increasing need for reliable storage systems, conversion‐type chemistry typified by bromine cathodes attracts considerable attention due to sizeable theoretical capacity, cost efficiency, and high redox potential. However, severe loss of active species during operation remains a problem, leading researchers resort concentrated halide‐containing electrolytes. Here, profiting from intrinsic halide exchange in perovskite lattices, novel low‐dimensional hybrid cathode, TmdpPb 2 [IBr] 6 , which serves not only as halogen reservoir reversible three‐electron conversions but also an effective absorbent surface Pb dangling bonds, C─H…Br hydrogen Pb─I…Br is proposed. As such, Zn||TmdpPb battery delivers three remarkable discharge voltage plateaus at 1.21 V (I 0 /I − ), 1.47 + 1.74 (Br /Br ) typical halide‐free electrolyte; meanwhile, realizing capacity over 336 mAh g −1 0.4 A retentions 88% 92% after 1000 cycles 1.2 4000 3.2 respectively, accompanied coulombic efficiency ≈99%.
