Abstract Potassium metal batteries are emerging as a promising high‐energy density storage solution, valued for their cost‐effectiveness and low electrochemical potential. However, understanding the role of potassiphilic sites in nucleation growth remains challenging. This study introduces single‐atom iron, coordinated by nitrogen atoms 3D hierarchical porous carbon fiber (Fe─N‐PCF), which enhances ion electron transport, improves diffusion kinetics, reduces energy barriers potassium deposition. Molten infusion experiments confirm Fe─N‐PCF's strong properties, accelerating adsorption kinetics improving deposition performance. According to Scharifker‐Hills model, traditional substrates without cause instantaneous nucleation, leading dendritic growth. In contrast, integration porosity promotes uniform progressive dense deposition, confirmed dimensionless i 2 /i max versus t/t plots real‐time situ optical microscopy. Consequently, X‐ray diffraction demonstrated stable cycling over 1900 h, while Fe─N‐PCF@K||PTCDA full cell retained 69.7% its capacity after 2000 cycles (72 mAh g −1 ), with voltage hysteresis 0.876 V, confirming potential high extended cycle life, paving way future advancements technology.

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.
