Abstract Low Na + and electron diffusion kinetics severely restrain the rate capability of MoS 2 as anode for sodium‐ion batteries (SIBs). Slow phase transitions between 2H 1T, from x to Mo S well volume change during cycling, induce a poor cycling stability. Herein, an original Fe single atom doped hollow multishelled structure (HoMS) is designed first time address above challenges. The in promotes transfer, companying with shortened charge path unique HoMS, thereby achieving excellent capability. strong adsorption self‐catalysis facilitates reversible conversion S. Moreover, buffering effect HoMS on improves cyclic Consequently, quadruple‐shelled sphere exhibits high specific capacity 213.3 mAh g −1 at ultrahigh current density 30 A , which superior previously‐reported results. Even 5 259.4 (83.68 %) was reserved after 500 cycles. Such elaborate catalytic site decorated also promising realize other “fast‐charging” high‐energy‐density rechargeable batteries.

Abstract Converting spent lithium‐ion batteries (LIBs) cathode materials into environmental catalysts has drawn more and attention. Herein, we fabricated a Co 3 O 4 ‐based catalyst from LiCoO 2 LIBs (Co ‐LIBs) found that the role of Al Cu current collectors on its performance is nonnegligible. The density functional theory calculations confirmed doping and/or upshifts d‐band center Co. A Fenton‐like reaction based peroxymonosulfate (PMS) activation was adopted to evaluate activity. Interestingly, strengthened chemisorption for PMS (from −2.615 eV −2.623 eV) shortened Co−O bond length 2.540 Å 2.344 Å) between them, whereas reduced interfacial charge‐transfer resistance 28.347 kΩ 6.689 kΩ) excepting enhancement above characteristics. As expected, degradation activity toward bisphenol ‐LIBs (0.523 min −1 ) superior prepared commercial CoC (0.287 ). Simultaneously, reasons improved were further verified by comparing with doped . This work reveals elements LIBs, which beneficial sustainable utilization LIBs.

Abstract Potassium metal is an ideal anode for potassium‐metal batteries due to its low electrode potential and high theoretical capacity. Nevertheless, infinite volume change, uncontrollable K dendrite growth, unstable solid‐electrolyte interfaces severely restrain practical viability. Inspired by the vertical channels in natural wood, a spatial control strategy proposed address above challenges using low‐tortuosity carbon matrix decorated with single‐atom Co catalysts that act as hosts (denoted SA‐Co@HC). The homogenously supported atoms on nitrogen‐doped reduce nucleation energy barrier promote deposition kinetics of K. Furthermore, conductive can alter electric field allow fast K‐ion transport direction. More importantly, SA‐Co@HC host provides sufficient channel spaces withstand tremendous change upon cycling. Benefitting from synergetic effects host, symmetric cell SA‐Co@HC/K composite demonstrates dendrite‐free potassium plating/striping behavior, well achieving superb cycling stability more than 2500 h at 0.5 mA cm −2 carbonate‐based electrolyte. full coupled potassium‐free organic cathodes, helps deliver excellent cycle rate performances compared bare anode.
