Quinone-based conjugated polymer cathodes synthesized via direct arylation for high performance Li-organic batteries.

Direct arylation cross-coupling reaction was employed to prepare quinone-based conjugated polymer cathodes, which realize a high reversible capacity of 200 mA h g -1 at 0.05 A g -1 , an excellent rate capability of 111 mA h g -1 at 30 A g -1 (150C), and a stable cycling performance for more than 3000 cycles.
