A redox-active porous polymer based on poly(imide-triazine) as a high-performance cathode for lithium-ion batteries

A dual redox-active porous polymer cathode provides very high discharge capacity (422 mA h g −1 at 0.5 A g −1 ), excellent rate capability (268 mA h g −1 at 10 A g −1 ) and long-term cycling stability (80% retention after 500 cycles and 65% retention after 4000 cycles).
