摘要

熔融聚合和机械球磨相结合，实现了聚酰亚胺共价有机框架（COFs）的简便量产，从而实现了高性能钠离子电池。实验证明，获得的 COF 具有较高的活性位点利用率（83.0%），孔径较小的 COF 性能更好，在 0.1 A g-1 的电流密度下，比容量为 213.7 mAh g-1。

Combining mechanical ball-milling with melt-polymerization to fabricate polyimide covalent organic frameworks towards high-performance sodium-ion batteries†

Melt-polymerization and mechanical ball-milling were combined to achieve the facile mass production of polyimide covalent organic frameworks (COFs) towards high-performance sodium-ion batteries. The as-obtained COFs were demonstrated with high utilization of active sites (>83.0%) and COFs with smaller pore sizes were proved to deliver better performance with a specific capacity of 213.7 mA h g⁻¹ at a current density of 0.1 A g⁻¹.
