Achieving Ah‑Level Zn–MnO2 Pouch Cells via Interfacial Solvation Structure Engineering

Caption

  • This work introduces sulfated nanocellulose as an anion-rich additive to tailor the Zn anode interfacial solvation structure, reducing interfacial H2O activity and suppressing hydrogen evolution.
  • In-situ attenuated total reflection Fourier transform infrared and fluorescence interface-extended X-ray absorption fine structure reveal the formation of a low-coordination Zn2+ solvation shell at the interface, facilitating rapid desolvation kinetics, enhancing interfacial stability during cycling.
  • Practical aqueous Zn–MnO2 pouch cells (1.5 Ah), underscoring the potential of interfacial solvation engineering for high-performance aqueous zinc-ion batteries.
