摘要：

Poly(N-vinylcarbazole) (PVK) containing the electron-rich carbazole moiety is exploited as a high-potential and high-capacity organic polymer cathode for dual-intercalation Na-ion batteries, which exhibits redox potential in the range of 2.5-4.6 V (vs. Na+/Na) and theoretical specific capacity of similar to 138 mAh g(-1). After proper optimizations, PVK can deliver average discharge capacities of similar to 110 mAh g(-1) for 100 cycles under a low current density (50 mA g(-1)) and similar to 62 mAh g(-1) for 900 cycles under a high current density (0.5 A g(-1)) using 1 M NaPF6 in ethylene carbonate (EC) and diethyl carbonate (DEC).
