The application of rechargeable magnesium batteries (RMBs) is hindered by the lack of suitable cathodes. Covalent organic frameworks (COFs) are considered promising as they have flexible organic polymer chains and an open structure. In this study, a new family of COF-based polyimide cathodes is synthesized and investigated as RMB cathodes. The COF cathode exhibits a high Mg-storage capacity of 120 mAh g-1, as well as high rate capability and good cycleability, suggesting that COFs could be a promising family of cathode materials for RMBs.
Rechargeable magnesium batteries (RMBs) attract interests as advantageous energy-storage devices, but the application is being hampered by the deficiency of suitable cathodes. Covalent organic frameworks (COFs) are promising selections because of the flexible organic polymer chains and open matrix. Herein, a new family of COF-based polyimide cathodes is synthesized and investigated as RMB cathodes. The COF cathode exhibits a high Mg-storage capacity of 120 mAh g-1, as well as high rate capability and good cycleability, suggesting COFs would be a promising family of cathode materials for RMBs.
