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

Abstract

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.
