High‑Performance Wide‑Temperature Zinc‑Ion Batteries with K+/C3N4 Co‑Intercalated Ammonium Vanadate Cathodes (IMAGE)
Caption
- Molecular dynamics and experimental results confirm that adjusting the interlayer spacing by changing the C3N4 content effectively improves the reaction kinetics.
- The synergistic effect of K+ and C3N4 co-intercalation lowers the energy barrier, reduces the electrostatic interaction, and enhances the kinetics and structural stability.
- The K+/C3N4 co-intercalated NH4V4O10 cathode exhibits excellent electrochemical performance at room temperature and under extreme environments.
