Abstract

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.
