Advanced nitrogen-enriched covalent organic frameworks: structural design and application mechanisms in zinc-based batteries
摘要
Zinc-based batteries face challenges of low capacity and poor cycling stability. Nitrogen-enriched covalent organic frameworks (N-rich COFs) offer promising solutions due to their ordered pores, tunable sites, and electron-redistributing nitrogen atoms, which enhance Zn²⁺ coordination and redox kinetics. This review summarizes N-rich COF structures, mechanisms, and electrochemical performance in zinc batteries, addressing future challenges.
