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 mAh g-1 at a current density of 0.1 A g-1.
