An organic Na-ion battery is reported with a polyanionic 9,10-anthraquinone-2,6-disulfonate (Na AQ26DS, 130 mAh g ) cathode and the Na-intercalated state (Na TP) of sodium terephthalate (Na TP, 255 mAh g ) as the anode. The resulting full cells deliver the maximum discharge capacity of 131 mAh g in 0.5-3.2 V, simultaneously maintaining the average value of ≈62 mAh g during 1200 cycles (0.5 A g , ≈4 C). These results are among the best performing organic sodium-ion full cells reported to date.
据报道，一种有机钠离子电池，其正极采用聚阴离子9,10-蒽醌-2,6-二磺酸钠（Na AQ26DS，130 mAh g），负极采用对苯二甲酸钠的钠嵌入态（Na TP，255 mAh g）。由此制成的全电池在0.5 - 3.2 V范围内的最大放电容量为131 mAh g，在1200次循环（0.5 A g，≈4 C）中同时保持平均值约为62 mAh g。这些结果是迄今为止报道的性能最佳的有机钠离子全电池之一。
