From Screening to Site Control: Phytic‑Acid Mediated P‑Tuning of M–N Coordination to Balance Iodine Adsorption and Stability in Zn–I2 Batteries

Caption

  • Systematic B/S/P heteroatom screening identifies P doping as the optimal strategy to realize coordination-tuned moderate iodine adsorption, addressing the critical adsorption-catalysis imbalance in Zn-I2 batteries.
  • A universal phytic acid-assisted one-step strategy is developed to fabricate core-shell single-atom catalysts, with synchronous P doping, cavity construction and metal site atomic dispersion.
