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...
