A biphase coupled cathode enables all-organic rocking-chair lithium ion batteries based on crystalline AB-stacked covalent triazine-based frameworks

Crystalline AB-stacked CTFs were synthesized in the AlCl 3 –NaCl–KCl ternary eutectic salt system, and a CTF-based biphase coupled cathode (BPCC) has been proposed and proved to show significantly enhanced electrochemical performance.
