Rechargeable potassium ion batteries have long been regarded as one alternative to conventional lithium because of their resource sustainability and cost advantages. However, the compatibility between anodes electrolytes remains be resolved, impeding commercial adoption. In this work, K-ion storage properties Bi nanoparticles encapsulated in N-doped carbon nanocomposites examined two typical electrolyte solutions, which show a significant effect on insertion/removal processes. KFSI-based electrolyte, N-C@Bi exhibit high specific capacity 255.2 mAh g−1 at 0.5 A g−1, 245.6 after 50 cycles, corresponding retention rate 96.24%. KPF6-based 209.0 71.5 an inferior only 34.21%. Post-investigations reveal formation KF interphase derived from salt decomposition intact rod-like morphology cycling K2 electrolytes, are responsible for better properties.

Abstract Sub‐nanoclusters with ultra‐small particle sizes are particularly significant to create advanced energy storage materials. Herein, Sn sub‐nanoclusters encapsulated in nitrogen‐doped multichannel carbon matrix (denoted as Sn‐SCs@MCNF) designed by a facile and controllable route flexible anode for high‐performance potassium ion batteries (PIBs). The uniformly dispersed can be precisely identified, which ensure us clarify the size influence on electrochemical performance. sub‐nanoscale effect of Sn‐SCs@MCNF restrains electrode pulverization enhances K + diffusion kinetics, leading superior cycling stability rate As freestanding PIBs, manifests properties, such exceptional ( around 331 mAh g −1 after 150 cycles at 100 mA ) capability. Especially, Sn‐SCs@MCNF||KFe[Fe(CN) 6 ] full cell demonstrates impressive reversible capacity 167 0.4 A even 200 cycles. Theoretical calculations that ultrafine beneficial electron transfer contribute lower barriers intermediates, thereby resulting promising Comprehensive investigation intrinsic process is revealed situ analysis. This work provides vital guidance design functional materials energy‐storage devices.

Low-cost graphite has emerged as the most promising anode material for potassium-ion batteries (PIBs). Constructing inorganic-rich solid electrolyte interface (SEI) on surface of is crucial achieving superior electrochemical performance PIBs. However, compositions SEI formed by conventional strongly solvating electrolytes are mainly organic, leading to structure being thick and causing co-intercalation behavior ions with solvent. Herein, a weakly applied weaken cation-solvent interaction alter cation solvation sheath structures, conducing inorganic composition derived from anions also participating in formation SEI, together forming uniformly shaped mechanical properties, thus improving overall The rich aggregated ion pairs (AGGs) (69%) enables remarkable intercalation at (reversible capacity 269 mAh g
