摘要

分子动力学和实验结果证实，通过改变C3N4含量来调节层间间距可以有效改善反应动力学。K+与C3N4共插层的协同作用降低了能垒，减小了静电相互作用，提高了动力学和结构稳定性。K+/C3N4共插层NH4V4O10阴极在室温和极端环境下均表现出优异的电化学性能。

High-Performance Wide-Temperature Zinc-Ion Batteries with K+/C3N4 Co-Intercalated Ammonium Vanadate Cathodes

Highlights

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.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
