N2 - Organic electrode materials with environmentally friendly, design flexibility at the molecular level are promising substitutes for inorganic intercalation materials as cathode for SIBs. However, traditional electrode materials usually perform poor cycling stability and rate performance, mainly due to the dissolution in electrolytes and low electronic conductivity. Herein, conjugated porous polyimide poly(2,6-diaminoanthraquinone) benzamide (CP-PDAB), was prepared from 2,6-diaminoanthraquinone and pyromellitic dianhydride by a simple polycondensation reaction. The obtained CP-PDAB has disordered aggregates with porous and loose structure, facilitating the penetration of electrolyte and volume change during charging/discharging. And the constructed conjugated skeleton with electron delocalization is beneficial for structural stability, insolubility in electrolyte and high electronic conductivity. When evaluated as cathode for sodium ion batteries, it can retain a high reversible discharge capacity of 141 mAh g-1 at 500 mA g-1 for 100 cycles, and can maintain the high specific capacity of 71 mAh g-1 at 10 A g-1 after 500 cycles. This work demonstrates the potential application of organic materials containing conjugated skeleton, porous and loose structure, and multiple redox active units for next generation electrochemical energy storage devices.
