Dual‑Ion Co‑Storage via Solvation Structure Tuning Toward Ultrafast and Durable Zinc‑Organic Batteries

Caption

  • Introducing KCl into ZnCl2 electrolyte induces salting-out and suppresses 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) dissolution.
  • The reversible Zn2+/K+ co-storage mechanism of the PTCDA cathode was unveil.
  • The assembled Zn//PTCDA battery exhibits superior electrochemical performance.
  • A high capacity of 124.7 mAh g−1 (91.7% of the theoretical capacity) at 1 A g−1 is achieved.
