Sodium 9,10-anthraquinone-2,6-disulfonate (Na AQ26DS), with polyanionic character and two O-Na ionic bonds, is found to be a highly stable organic cathode in Na-ion batteries, delivering capacities of approximately 120 mAh g for 300 cycles (50 mA g ) and around 99 mAh g for 1000 cycles (1 A g ). These results are the best performance reported to date for small-molecule, anthraquinone-based organic cathodes in Li-, Na-, or K-ion batteries.
9,10-蒽醌-2,6-二磺酸钠（Na AQ26DS）具有聚阴离子特性和两个O-Na离子键，被发现是钠离子电池中一种高度稳定的有机阴极，在300次循环（50 mA g）时提供约120 mAh g的容量，在1000次循环（1 A g）时提供约99 mAh g的容量。这些结果是迄今为止锂、钠或钾离子电池中基于蒽醌的小分子有机阴极所报道的最佳性能。
