Abstract Mn‐containing sodium superionic conductor (NASICON) compounds have shown considerable potential as cathode for sodium‐ion batteries (SIBs) owing to higher working voltage (V 5+ /V 4+ : 3.9 V), lower cost, and toxicity compared full vanadium‐based NASICON Na 3 V 2 (PO 4 ) . Taking 3.3 1.7 Mn 0.3 (NVMP) an example, its practical application is still restricted by poor electronic conductivity, sluggish intrinsic + diffusion, high‐voltage stability. In this work, a high entropy strategy proposed develop 1.613 (Cr, Fe, Co, Ni, Zr) 0.1 (HE‐NVMP) not only enabling more rapid migration but also significantly improving deep desodiation Based on theoretical calculations experimental findings, such modification can efficiently alter the coordination environments of both V/Mn sites reducing diffusion energy barrier, increasing occupancy at Na(2) sites, consolidating structure Thus, obtained HE‐NVMP delivers superior high‐rate capability (91.7 mAh g −1 up 50 C excellent cycling performance (capacity retention: 81.2%) after 10 000 cycles 20 cutoff 4.1 V. More importantly, exhibits storage properties (4.5 V) with electrochemical polarization 75% reduction 1 capacity retention 80.3% 2000 pristine counterpart, indicating great rechargeable overcharge resistance capability.

Abstract High entropy alloys (HEAs) with entropy‐driven stabilization are attractive in potassium‐ion batteries (PIBs); however, they suffer from phase segregation due to the disparity of versatile components. Confining multifarious metals into same lattice using ligands full‐coordination abilities allows for delicate control at nanoscale level and thus decreases atom diffusion. This chemical synthesis can suppress realize HEAs PIB anodes. Herein, a new MnCoNiCuZn‐based HEA nanoparticle encapsulated within nitrogen‐doped carbon (HEA‐NPs@NC) is fabricated The flexible chlorhexidine selected its long chain, large steric bulkiness, abundant neutral tetradentate donors, coordination ability. high effect “cocktail” HEA‐NPs@NC allow tailoring electrochemical functionalities, including multiple K + transport paths, good conductivity, stability. anode achieves lifespan over 3000 cycles, impressive capacity (513 mAh g −1 ), high‐rate performance (202 5 A ). ex situ characterizations density functional theory calculations elucidated acts as an “atomic composite” forms interstitial metallic solid solutions interaction constituent elements.
