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

Abstract

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).
